How to Troubleshoot Your Keyboards

2009-09-16T09:22:00.000Z

Imagine a computing world without a keyboard. Doesn’t seem plausible, does it? Though they’re often taken for granted, keyboards are vital toward helping us input data into email, Word and Excel documents, Websites, and more. They also let us quickly open Windows programs, execute commands, control multimedia content, and play games. If you’ve experienced a keyboard related problem, you know computing life seemingly stops until the problem is rectified. Depending on whether you use a notebook or desktop system, your keyboard likely has 80 to 110 keys and uses a traditional QWERTY layout vs. a Dvorak or other layout. Most keyboards connect to a computer via a cable that has a connector that plugs into a computer PS/2 or USB port. The connection provides the keyboard power and relays electrical signals between the keyboard and computer. Wireless keyboards typically use battery power and a receiver that you connect to the computer for communicating, usually via RF (radio frequency) or Bluetooth technology. Inside a keyboard, a built-in microprocessor and circuitry manages those electrical pulses, which occur when you press a key and it connects to a sensor that’s underneath. The microprocessor, or controller, analyzes the pulses, converts them to binary form, and passes them to the operating system, which executes the appropriate command or enters content into the proper program.

Fortunately, keyboards are fairly simple devices and don’t generally experience many problems. Still, there may come a time when you notice incorrect characters or no characters at all displaying on-screen, multimedia keys not functioning, error messages indicating a keyboard isn’t present, or keys sticking. The following are common keyboard-related problems and possible fixes.

Simple Problems, Simple Solutions

Most keyboard problems usually relate to the keyboard’s cable, proprietary software, its cleanliness, or mechanical failures. Fortunately, most of these problems are easily corrected.

Problem: Your keyboard only types capital letters or the numeric keypad won’t display numbers or text you enter overwrites existing characters.

Solution: These problems are usually caused by keys with functions you can toggle on and off. For example, if the keyboard only displays capital letters, the CAPS LOCK key is probably on. Press it to turn the function off. The same applies to the NUM LOCK, INSERT, and SCROLL LOCK keys.

Problem: You’ve spilled fluid on the keyboard.

Solution: Drink enough coffee, soda, or other beverage around your computer, and accidents are bound to happen including spilling liquid on your keyboard. If this happens, acting quickly is imperative, as the underlying circuitry is in immediate risk of being permanently damaged. To (hopefully) rescue the keyboard, first shut your system down to turn off electricity to it and then tip the keyboard to drain as much fluid as possible. Follow up by wiping it with a dry rag or towel. If the fluid was something other

than water, use warm water to wipe the board clean. Some experts advise rinsing the entire board. If you do, make certain the keyboard is completely dry before plugging it back in, as electricity and water don’t mix. Using a hair dryer can accelerate the drying process, especially underneath the keys, but take care not to damage the circuitry with excessive heat. For safety reasons, consider waiting several days before using the keyboard again. If these steps don’t do the trick, a replacement is probably necessary.

Problem: Certain keys stick when you press them.

Solution: Your keyboard will usually let you know if a key is sticking by ringing out a continuous beep, indicating the keyboard’s memory buffer is packed. Otherwise, characters may display erratically, or you’ll physically feel the key is stuck. Keys stick for several reasons, including if the board is particularly dirty. Over time, keyboards accumulate significant dirt, dust, and debris on and under keys. A cloth tissue with a little water usually is enough to clean the board’s surface, and using a can of compressed air will clear most junk from underneath the keys. If you still notice keys sticking, power your system down and try to gently pry off the stuck key with a flathead screwdriver, cleaning the space with a cotton ball and some isopropyl alcohol.

Beyond The Basics

Although most keyboard-related problems aren’t severe, a few go beyond a cable simply being loose. The following problems require a bit more effort to resolve.

Problem: Your computer isn’t recognizing your keyboard.

Solution: If Windows displays an error message that a keyboard isn’t present or characters you type aren’t displaying on-screen, check the connection to the computer. Shut your system down and then look at its back to make sure the connector is securely plugged into the proper PS/2 or USB port. PS/2 keyboard ports are typically colored purple, and the connector will only fit one way. Check also that the connector’s pins aren’t bent or broken. It’s possible to gently bend a pin back in place, but if it’s broken, replacing the keyboard is your only option. If the pins are fine but you suspect the board isn’t receiving power, plug another keyboard into the computer. If it works, your keyboard’s circuitry may be damaged, and you’ll likely need a replacement. If the substitute also fails, the PS/2 or USB port or a motherboard controller may be bad, and it’s possible you’ll have to replace the motherboard.

Finally, if the keyboard is plugged into a USB hub, the hub may not be capable of supplying sufficient power to the keyboard. Try connecting the keyboard directly to a dedicated USB port.

If you see error messages indicating a keyboard isn’t present,

it could mean your keyboard cable is unplugged, loose, or

plugged into the wrong port. Most keyboards plug into a purple

PS/2 port or USB port. Make certain the board isn’t plugged

into the green PS/2 port for mice.

Problem: The multimedia or quick-launch keys won’t work.

Solution: Many keyboards include special keys for controlling multimedia content, such as adjusting volume levels, or for opening commonly used programs, such as a Web browser. Accessing these functions or customizing the keys usually requires installing proprietary software and a device driver that the keyboard’s manufacturer provides. If these keys aren’t working, check that the software is installed and the configurations set correctly. Check also that the keyboard meets Microsoft’s compatible tests.

(You can check at testedproducts.win dowsmarketplace.com.) If your board isn’t listed, check with your manufacturer for updated software.

Problem: You accidentally turned on StickyKeys and can’t turn it off.

Solution: Windows provides the StickyKeys tool for those who have trouble holding down two keys at once, such as CTRL-Z. With Sticky-Keys turned on, you can push one key one at a time to perform a key combination. Pressing the SHIFT key five times turn StickyKeys on. Pressing SHIFT five times again turns it off.

Problem: Characters repeat onscreen when you type.

Solution: If characters consistently and unintentionally repeat on-screen, adjusting the sensitivity of your keyboard’s keys can help. Do this in Windows XP by clicking Start and Control Panel and then double-clicking Keyboard. On the Speed tab, use the sliders under Repeat Delay and Repeat Rate to experiment with how long you have to hold a key down before it repeats and the rate at which repeated characters display. When you find a setting you’re comfortable with, click OK.

Other Road to Success

Other options for curing what’s ailing your keyboard include checking if Device Manager shows the keyboard as being problematic. In WinXP, click

Start and Control Panel and then double-click System. In the System Properties dialogue box, click the Hardware Tab, click Device Manager, and look for the Keyboards entry. If your see a yellow exclamation mark or red X, there is a problem. Highlight the keyboard and click the Uninstall button. Reboot the system, and Windows will reconfigure the board. If your board displays odd characters on-screen, check that Windows is using the correct language setting by opening Control Panel and double-clicking Regional And Language Options. On the Languages tab, click Details and check that English (United

States) – US is set as the default. If not, click the Add button under Installed Devices and select it from the dropdown menu.

You Can’t Install Something ...... read this

2009-09-13T12:13:00.000Z

It all seemed like such a good idea at the time. You picked up the newest, coolest video-editing suite this afternoon and spent the whole drive home thinking of how your video creations were going to put Martin Scorsese to shame. However, every time you tried to install the software, your computer coughed up some new and exotic error that gave you no idea as to what the actual problem was. While the causes of install errors are many and varied, we’ve got you covered with some of the most common ones—and how to go about fixing them.

Insufficient Resources

There’s one error that you may be able to circumvent before even buying the software. Too often, you can trace installation problems back to insufficient system resources. Most software manufacturers list the system requirements for their products right on the software packaging itself, but that helpful information really means nothing if you don’t know what you’re looking at or what resources your system has.

Let’s take a look at your system’s resources. In Windows XP, simply click

Start, then Control Panel, then double-click System. In the window that pops up, click the System tab. Under the System heading, you’ll find your current operating system, as well as the Service Pack that’s currently installed. In the lower-right quadrant of this window, you’ll find information on your processor speed and available memory. Take note of all of this information; if your system’s specifications don’t match or exceed the requirements listed by the manufacturer, then the software won’t properly function on your computer. Some software packages will also have specific requirements for your video card, as well. While still in the System Properties window, you can check these by clicking the Hardware tab and then clicking the Device Manager button. To see what kind of video card your system has, click the plus (+) symbol next to the Display Adapters icon. (You can also find this information by double-clicking the

Display icon in the Control Panel and then clicking the Settings tab; the video card should be listed under the Display: heading about halfway down.) One final note about system requirements: Manufacturers will often list minimum system requirements as well as recommended ones. Though the software may work with the minimum requirements, it’s probably a good idea to make sure that your system has the recommended ones because the programs you install will generally run a lot smoother and crash less if your system doesn’t have to use every bit of its resources just to load them.

Do You Have Permission?

Another common problem users run into when installing new software, especially on newer machines, stems heavily from something called user permissions. Machines running Windows NT/2000/XP are all configured with an Administrator login, which is usually included so that normal users can’t access certain parts of the computer. You’ll know you have a problem with user permissions when your error message includes the words “Please contact your system administrator.” Of course, you probably don’t have

a system administrator. You’re probably running the computer at home, not at an office. So why is your computer asking you to contact someone who probably doesn’t exist? will give you a fresh error that’s related to installation.

You can find a wealth of information on your

system in the System Properties window.

You can sidestep a large number of

Installation headaches if you make sure

to log in as an Administrator before you try

adding any new software to your system.

The problem here is that many types of software cannot install properly if there is an older version of the same software already present on the computer. Though this error can be frustrating, it’s fortunately rather easy to fix. Click Start, then Settings, then Control Panel. Double-click the Add or Remove Programs icon. A list of the software that is currently installed on the machine should appear. Scroll down through the list until you find a match for the software you’re trying to install (for example, if you’re trying to install the newest Adobe Flash Player, check the list for any mention of that name). When you do find a match, click the software name and then click the Change/Remove button. Your computer will uninstall the old version of the software. Sometimes, Windows will require you to restart your computer to complete the process. Once the computer is finished rebooting, log in as an Administrator and then try installing the software again.

If It Isn’t the Software

So far, we’ve mainly covered software installation problems, but another set of errors can cause just as much frustration for the average home user. Instead of purchasing the newest, coolest video-editing suite, you’ve instead just purchased some new hardware, in the form of a DVD-R drive for your machine. You followed the instruction sheet to the letter, but when you turn your computer on, the new component still won’t work. What gives? There are many reasons why a newly installed piece of hardware might not work, but we’ll cover three of them in general here. The first reason should look rather familiar, as it’s also a common cause of software installation problems: system requirements. Check in the hardware’s packaging, and make sure your machine meets or exceeds the manufacturer’s requirements for the new part to operate. If your system requirements are in order, make sure that your machine has the correct drivers installed to run the new piece of hardware. These will usually come in the box with the new hardware, most often on a CD. Run this CD to install the proper set of drivers for the new hardware. Also, the hardware manufacturer’s Web site may also have the driver for the hardware available for download. Now that the drivers are installed in your well-above-specs system, everything should work as advertised. If it doesn’t, however, you may want to check for a device conflict. This error occurs when more than one device is trying to use the same resource or set of resources on your computer. To see if this is the case, open the Device Manager as described above and then check the list for any piece of hardware that registers a device conflict (there will usually be a red exclamation mark in a yellow circle next to the names of such devices).

Can’t Delete Something? ....raad this

2009-09-12T19:05:00.000Z

Deleting something is usually one of the easiest computing tasks to accomplish. So much so that OS (operating system) developers such as Microsoft (www.microsoft.com) have added safeguards to their products to make sure trigger happy users think twice before deleting the wrong file and doing irreparable harm to their data or systems.

But there are times when the simple act of deleting something can go awry.

The causes are many, from the simple to the exotic, but they all have one thing in common: They can be extremely vexing and frustrating when you just want to, well, throw out the digital trash.

Working Status

Deleting a file is usually quite simple. The application that you’re working in may provide you with a warning before you delete a file, asking you to confirm that you indeed want to delete the file before proceeding. Once confirmation is given, that’s all it takes. Windows versions since Windows 95 all feature the Recycle Bin, the trash can icon on your Desktop that temporarily stores deleted files. The Recycle Bin is there in case you have second thoughts and decide you need a deleted file after all and is just an area on your hard disk set aside to temporarily hold files marked for deletion. Files stored in the Recycle Bin may last for a while, depending on the size of the Bin. (By default, Windows makes the Recycle Bin 10% of whatever the hard disk capacity is.) But be aware that the Recycle Bin doesn’t exist in certain situations. For example, if you delete a file stored in a thumb drive, there won’t be any Recycle Bin to bail you out if you change your mind. Ditto for network drives, which usually don’t have a Recycle Bin either; usually, a file stored in a network drive is immediately deleted. But, since network drives are frequently backed up by businesses, there may be a copy of the file that you can retrieve from backup media if you accidentally delete something you needed after all.

Try, Try Again

You try to delete a file, but you receive a warning telling you the file can’t be deleted. When this occurs, the first step is to determine whether the file is in use by a program. For example, if you attempt to delete a file that is open in Microsoft Word, switch to Word and then close the file within Word. Once you close the file in Word, you should be able to delete it with no problem. In most cases, Windows XP tells you the application that is using the file in question, so it’s pretty simple to close the file and then delete it. You can also get a clue as to the application that is using the file by the file’s icon or the extension. For example, if a file extension is .PDF (Portable Document Format), you know this is an Adobe Acrobat (www.adobe.com) file that is viewed using Adobe Acrobat or Adobe Acrobat Reader. Sometimes, even closing an application using a file isn’t enough. This can happen because an application does not play nice and refuses to let go of the file even though the application is closed. In some cases, an application may appear closed (you exited the application), but it is still running in the background.

For example, some applications don’t close all the way when you exit but continue to run in the background. These apps may appear as a small icon on your System Tray (the area in Windows on the lower-right portion of the screen where you may see a number of small icons). If you suspect this is the problem, simply locate the application’s icon in the System Tray and close the application. For most programs, right-clicking the System Tray icon will launch a small menu that contains an Exit or Close command. Click the appropriate command and then delete the file. If the application using the file you want to delete is closed, there is no System Tray icon, and you still can’t delete the file, you may be grappling with a poorly programmed app that refuses to release a file even after you exit the application in the normal way. To close this type of stubborn program, press CTRL-ALT-DELETE to launch the Windows Task Manager. Click the Processes tab and look through the list of programs and processes running in your system. Unfortunately, the contents of this list are usually program names ending in .EXE or file names ending in .DLL, so things may appear a bit cryptic. Usually, the name of the program executable file for an application matches the name of the application: For example, Excel’s program executable file is Excel.exe. Scan the list, find your application’s executable file, and click the End Process button to close it. If the name of the application’s program executable file is not obvious, browse to the program folder that contains the application’s program files. To do this, double-click My Computer, Local Disk (C:), and the Program Files folder. Scroll through the list of folders until you locate the folder containing the program in question and then double-click it to open it. Look for file names ending with .EXE; one of those will be the app’s main program executable, which you can then close using the Windows Task Manager’s Processes tab. If all else fails, the inability to delete a file may be an indicator of file system corruption. This means the area of the hard drive where the file is stored is corrupted. This could be due to a software or hardware issue. For example, if an area of your hard drive is physically damaged, strange behavior can occur. To have Windows find and correct file system errors, click Start, All Programs, Accessories, System Tools, and Disk Defragmenter. Click the Analyze button in the Disk Defragmenter window. Windows will look for file system errors and correct anything it finds, if possible. Now try to delete. If you still can’t delete the file after trying this software fix, there may be serious errors with your hard disk signaling an impending hard drive failure. And that is a real problem requiring swift action. Back up your important files and replace the hard disk as soon as possible.

Video File Issues

It is possible that you may receive an Access Denied or Windows Can’t Delete The File Because It’s In Use error message while trying to delete a file ending in the .AVI (Audio Video Interleave) file extension. This problem can occur because WinXP creates thumbnails for video files (such as AVI files) that show the first frame of the video. This makes it easy for users to see what video content a file contains without having to open it. To provide this functionality, WinXP uses a file called the Shell Media Extension (Shmedia.dll). This feature usually works perfectly, but whenever a video file is corrupted or not playing nice with Shmedia.dll, the system “locks” the file and doesn’t release it, even after you reboot. To solve this problem, you can do one of two things. First, you can open up a command line by clicking Start and Run and typing cmd in the text box. At the command prompt, type CD drive where file is stored:\folder where file is stored and press ENTER. For example, if the file is kept in a folder called Video in your C: drive, type CD C:\Video to open the folder. Type dir at the command prompt to see the list of files contained in the folder and then type DEL file name (where file name is the name of the file you want to delete) to delete the file. If the name of the folder is greater than six characters, you must shorten it by entering ~1 after the first six characters. For example, if the name of the folder you are trying to get to is called Program Files, to open the folder from a command prompt you must type CD C:\progra~1 to open the folder. That’s because the command prompt environment can’t handle long file names. The second approach requires modifying your Windows Registry. (NOTE: Making changes to the system using the Registry Editor may cause errors that render the operating system unstable. You should always create a backup before editing the Registry.) To do this, click Start and Run and then type regedit in the text box. With Registry Editor open, locate the following key: HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler\{87D62D94-71B3-4b9a-9489-5FE6850DC73E}. Click the key in the right-hand pane of the Registry Editor to highlight it, right-click the key, and select Delete from the context menu. You’ll give up the thumbnail previews of video files feature, but you’ll now be able to delete the offending AVI file.

The Processes tab in the Windows Task Manager
window shows a list of all processes currently
running in your system. In some cases, this may
be the only way to close an application that
refuses to release a file you want to delete.

For Your Own Protection

You keep deleting a file in one of your Windows system folders, but whenever you open the folder that contained the file, the file is there again. What’s going on? To prevent users from accidentally destroying their Windows installations, Win2000/XP contains a feature—which is enabled by default—called Windows File Protection. (The feature is called System File Protection in WinMe.) If you delete a file that Windows deems important, that file is automatically restored to its proper location from a cache of critical files that Windows keeps on your hard drive. If you’re trying to delete a file located in any of the Windows system folders, chances are you won’t be able to do it unless you disable Windows File Protection. And disabling Windows File Protection, while straightforward, requires some editing of a DLL file using a hex editor. Unless you have a really good reason to do this, you’re better off leaving Windows File Protection alone. It’s there for your protection. Only technically savvy users who are very experienced at tweaking and customizing their systems should attempt to remove Windows File Protection and delete files stored in the Windows system folders.

What To Do When You Accidentally Delete Something

2009-09-11T09:02:00.000Z

At some point in your computing life, you will lose data, whether it’s due to something as serious as a system crash or something less drastic but equally as frustrating, such as accidentally deleting a file. While the sting of losing a coveted photo, spreadsheet, or audio file definitely smarts, it may ease your pain knowing there’s a good chance of getting your data back if you act quickly and logically.

For this article we’re assuming you’ve accidentally deleted or misplaced a file, folder, icon, or similar data and a backup copy isn’t available. Data lost to such problems as malfunctioning hardware/software or Windows- related errors often require more time-consuming and complicated solutions—uninstalling/reinstalling Windows, using Windows’ Repair or Recovery Console utilities, replacing a hard drive, and more—than those we’ll discuss here, which are generally easier to execute but potentially as effective. First, though, it will help to know what you’re dealing with when you lose data, accidentally or otherwise.

Where Deleted Files Go

Many users assume once a letter, photo, song, or other file is deleted that it’s gone for good, but this isn’t the case. Deleting a file essentially only erases the bookmark that Windows uses to retrieve the file. What deleting a file really tells Windows is that you no longer wish to reserve hard drive space for the file. Thus, the file remains on your drive until Windows writes over it with new data. Until then, there’s a chance of retrieving your accidentally deleted data. Initially, the best thing you can do is actually nothing, as any new data you save to your hard drive could write over the file you want to retrieve.

Also, running a disk defragmenter could wreak havoc on your deleted file. If you’ve scheduled Windows’ Disk Defragmenter to run automatically, disable the option (click Start, Programs, Accessories, System Tools, Scheduled Tasks) until you retrieve the data. Ultimately, getting your file back may mean using an undelete program. At worst, a data recovery service can retrieve data from even a presumed dead hard drive, but typically at a stiff price (more on these options later).

Search For Your Files

Often, just searching for a file can tell you if you really deleted it or accidentally saved it to another location. First, check the list of recently accessed programs and files WindowsXP keeps at the left of the Start menu. Windows programs such as Wordand Excel also keep a list of recently opened files specific to that program on the File menu. Clicking the File menu in Word, for example, shows you four recently accessed Word documents and their locations. Another option is Windows’ Search tool (click Start, Search). In the Search Results dialogue box under the Search Companion pane are options to search for Pictures, Music, Or Video; Documents (Word Processing, Spreadsheet, Etc.); All Files And Folders; and Computers And People. Try clicking All Files And Folders and entering appropriate text in the All Or Part Of The File Name and A Word Or Phrase In The File text fields. Next, click My Computer from the Look In drop-down menu and click Search. Your results will display to the right. If Search doesn’t find what you’re after, try using a wildcard (*) character and the document’s file extension, such as *.doc or *.xls. Search also has such advanced search options as Search Hidden Files And Folders and searching by file size, last modified date, and other criteria.

Check The Recycle Bin

If Search proves fruitless, check that Windows isn’t holding the file in the Recycle Bin (double-click the Recycle Bin Desktop icon). Most files you manually delete remain in the Recycle Bin, taking up hard drive space until you empty the bin (click File and Empty Recycle Bin). By default, the Recycle Bin uses 10% of your hard drive’s capacity (change this by right-clicking Recycle Bin, clicking Properties, and adjusting the Maximum Size Of Recycle Bin slider.) When the capacity is full, Windows drops off older files as new ones are added. If you have a large-capacity hard drive, your files can remain in the bin for a long time. If your file is in the Recycle Bin, highlight it, click File, and click Restore to retrieve it.

Use System Restore

System Restore is Windows’ utility that can roll your system’s settings back to a previous date, or Restore Point. System Restore doesn’t alter files you’ve recently created, such as email and Word docs. Using a Restore Point will remove any Windows updates or program-specific upgrades (particularly virus and spyware definitions) you installed after the Restore Point’s date. You’ll need to reinstall these after the restoration. To use System Restore, click Start, Programs, Accessories, System Tools, System Restore, and follow the steps given.

Use Undelete Software

If your file is still missing, it’s time to consider using an undelete program, which will scan your hard drive for data that’s still active but that Windows doesn’t recognize. Note, however, that an undelete program may only retrieve portions of a file due to several reasons, including how Windows stores data. Rather than save a file in one location on a hard drive, Windows chops the file into smaller chunks, or clusters, that it fits into spaces on the drive as they become available. These spaces usually aren’t next to one another, and as new data is saved to a drive, it can write over various portions of the file. Although undelete programs range in price and difficulty of use, most can also scan removable storage devices and include a search tool and helpful filters for narrowing down searches. Many free undelete apps are available, but most will only display the files they can retrieve until you pay the program’s full version to retrieve them.

To make certain you really accidentally deleted

a file and didn’t actually save it to another location,

use Windows’ Search tool to (hopefully) find the file.

When looking at undelete apps, consider one that you can download to and run from a removable storage, such as a CD/DVD, floppy diskette, or USB keydrive, as, again, installing an app to your hard drive could write over the files you want to retrieve. Additionally, although programs differ in how they search for retrievable data, most offer quick and deepscanning options and filters for searches and viewing results. This last point is important, as typically a program will return hundreds to thousands of files that may date back years. Finally, look for an app that rates the chances of retrieving files, such as PC

Tool’s File Recover does using Poor (partially recoverable) or Excellent (fully recoverable) qualifiers. For this article we used various demo, free trial, and final versions of PC Tools’ File Recover ($29.95; www.pctools.com), WinRecovery Software’s WinUndelete ($49.95; www.winundelete.com), OfficeRecovery’s Free Undelete (free; www.officerecovery.com), Executive Software’s Undelete 5.0 Home ($29.95; www.executive.com), and R-tools Technology’s RUndelete ($54.99; www.r-undelete.com). Other apps include Que-Tek Consulting’s File Scavenger 3 ($49; www.quetek.com), Active@DataRecovery’s Active@File Recovery ($29.95; www.file-recovery.net), and Stompsoft’s Recover Lost Data ($39.99; www.stompsoft.com). Wellknownmanufacturers such as Symantec (Norton SystemWorksStandard, $69.95; Save & Restore, $49.99; Norton Ghost 10, $69.99; www.symantec.com) and McAfee (Internet Security Suite, $49.99; www.mcafee.com) also offer recovery tools.

Use A Data Recovery Service

Depending on how valuable your lost data is, a data recovery service is an excellent option. The bad news is that such services are typically time-consuming and expensive, ranging from hundreds to thousands of dollars. Typically, after evaluating the drive, the service will provide a cost estimate for getting your data back. Further, you may get multiple estimates based on different factors that may influence the ability to get back your data, such as if the hard drive is physically damaged.Before choosing a service, ask what data you can expect it to retrieve, including the specific data you want back. Check if the company performs retrievals in its offices, onsite, or offers software you can operate yourself at home. Most importantly, make certain the company adequately answers all privacy-related questions, as the service will have access to all the data on your hard drive, including personal information. Two data recovery services include DriveSavers (www.drivesavers.com) and Ontrack Data Recovery (www.ontrack.com/services). Overall, some preparation is often the best solution for getting accidentally deleted data back. This means routinely backing up important files and having an undelete program on hand so you can immediately search for the file after you realize it’s gone. Additionally, many Windows programs have auto-save and backup features, such as Word’s Always Create Backup Copy setting (Click Tools and Options and click the Save tab).

What to Do If Your PC Starts Slowly

2009-09-10T06:50:00.000Z

Don’t let your PC start like a tortoise

PCs that boot slowly are among the most common complaints users have, but there’s slow and then there’s slow. A computer that needs a minute between pressing the power button and letting you start a program is perfectly normal, even if those 60 seconds may feel like an eternity. A computer that takes a little longer may be suffering from a minor problem (or might just be an older machine), but a computer that takes four or five minutes (or more!) to get rolling is almost certainly suffering from one or more problems that need your attention. Most slow-boot problems have to do with software; specifically, there’s too much software running automatically when Windows boots, but this shouldn’t be the first thing you attempt to tackle. You should check hardware problems first. Follow that by checking for spyware and viruses, because these issues can undermine even the most thorough, intricate software cleaning job. And if you notice your boot process suddenly taking longer after recently adding new hardware or software, you may have already determind the root of your startup problem. Finally, although there may indeed be a smoking gun—a large, single problem causing the delay—long boots are frequently a result of many small delays and inefficiencies added together. Booting a computer requires dozens of sequential steps, so it’s certainly possible to save 60 seconds by eliminating 10 six-second delays.

Lavasoft’s Ad-Aware SE, often your first line of

defense against spyware, can purge

malware that’s plaguing your startup.

Basic Hardware Checks

It isn’t uncommon for a computer to slow as one or more of its components starts to fail, and a slow boot may just be the only noticeable symptom.

Although the BIOS (Basic Input/Output

System) is unfamiliar territory, making a few

changes could speedup your system.

Fortunately, performing tests and checking the obvious is fairly easy. First, take a deep breath, open up the computer (assuming it isn’t a laptop), and turn it on. Check that all the fans are spinning. Some fans are temperature-sensitive and won’t speed up (or even start spinning) until things are warm, so consider leaving it running this way for a little while. Make a note of any fans that seem dead; have a professional replace them or, if you know what you’re doing, replace them yourself. Next, turn the PC off and take a good look at the CPU’s heatsink. (You may have to remove a plastic shroud that surrounds the CPU.) If it’s covered with dust and grime, clean it with a can of compressed air (readily available at most electronics stores) or a small brush. This ensures the CPU is cooling itself properly, because most modern CPUs throttle back to a lower clock speed if they’re overheating. And a lower clock speed can contribute to a slower boot process. A marginally working CPU, hard drive, or memory module can also slow the boot process down, especially when the failing component still “sort of works.” For example, a failing hard drive might finally work after 10 attempts at reading from it, and Windows may retry using that failing hard drive many times before giving up. Fortunately, we recommend a free bootable CD called the Ultimate Boot CD, which you can download from www.ultimatebootcd.com. It has dozens of generic tests for your CPU and memory and includes all the major hard drive manufacturers’ hardware tests. And because it’s a bootable CD, you don’t need to load Windows (and, after all, loading Windows is really the problem in the first place) to run the disc’s tests. You can run through all the CPU tests in a few minutes, but let one of the memory checkers run overnight. The hard drive tests will only need a few minutes to do a quick check, but if you can spare another night, opt for running a deep test for better results. If your hardware checks out, you can move on.

BIOS Tweaks

When you fire up your PC, its BIOS (Basic Input/Output System) leaps into action, initializing hardware, testing RAM and other hardware, and looking for a bootable device. You can alter the tasks it performs by accessing your system’s BIOS setup. Immediately after you turn on your computer, take a close look at the screen for a message such as “Press F2 To Access BIOS Setup” or similar language and press that key. Your PC’s/motherboard’s users manual should also identify the appropriate keystroke. With luck, it may even describe some BIOS options. If your goal is to eliminate as many small delays as possible, then there area few changes you can make to your BIOS. First, look for an option called Quick Boot and enable it; this eliminates some of the system tests during the boot. This feature’s name may vary on a different BIOS, but you should generally enable any option that appears to accelerate your boot speed. Next, move to the Hard Drive Detection (sometimes called IDE Detection) screens, and switch the IDE (Integrated Drive Electronics) positions you know to be empty from Auto to None—in other words, if you don’t have a Primary Slave IDE drive, set Primary Slave to None. You can identify an IDE drive by the flat, wide cable that connects the drive to the motherboard, but when you start making changes to your BIOS, always be certain you understand exactly what you’re changing. And if your system only uses SATA (Serial Advanced Technology Attachment) drives, then set all the IDE positions to None. Finally, if you never boot from a floppy diskette drive, CD/DVD ROM drive, USB device, or network connection, set the hard drive as your first boot device. This prevents your PC from checking for bootable media elsewhere every time.

Clearing Bad Parasitic Software

After you’ve eliminated any hardware issues and streamlined your BIOS, it’s time to deal with the bad software: viruses and spyware. If your computer boots slowly but works reasonably well once it completely boots, any malware that’s snuck into your system is probably a minor infestation, which means it’s probably one you can clear with automated tools. If you have antivirus software installed, it’s time to update your definitions and run a full scan. And if your commercial antivirus subscription (for example, Norton AntiVirus) has expired, either renew your subscription or uninstall what you have and install a free antivirus product, such as AVG Anti-Virus Free (free.grisoft.com) or AOL’s Active Virus Shield (www.activevirusshield.com). Because viruses evolve rapidly, it’s critically important to use an antivirus product with current definitions. Don’t bother with out-of-date antivirus software. Spyware can also bog down your boot, so you should clear that, too. Like antivirus software, antispyware products need current definitions to do an effective job, so update what you have before running a full system scan.

Although the BIOS (Basic Input/Output System)

is unfamiliar territory, making a few changes

could speedup your system.

If you don’t have any antispyware tools and don’t think you have a serious spyware problem, then try a couple of free programs to be safe. Most of the free scanners don’t have always-on components, and different scanners tend to focus on different types of threats; you can usually install a few and let them scan without worrying that one program will interfere with another. Two that work well together are Ad-Aware SE (www.lavasoftusa.com) and Spybot Search & Destroy (www.safer-networking.org). Perform each application’s antispyware scan individually instead of running them simultaneously.

Clearing “Good” Parasitic Software

It should come as no surprise that software often installs itself to automatically run every time Windows starts, but the sheer volume of this particular software that’s running on your system may shock you when you count it all up. Limiting your software that starts on boot to just the programs, utilities, and drivers you always need can dramatically reduce boot times. There are two challenges to face here. The first is finding a list of programs that start automatically, and the second is to know which programs you can safely disable at boot time. Fortunately, there’s a handy tool that’s built into every version of Windows (except Windows 2000) that shows you almost all your auto-start programs: msconfig. To run it, click Start and Run. Type msconfig and click OK. Next, click the Startup tab to see the auto-start list; a check mark next to an application means that it’s starting every boot, while an empty checkbox means the program is disabled.

If you have Win2000 or want a more advanced tool, then try using AutoRuns for Windows (www.microsoft.com/technet/sysinternals/utilities/Autoruns.mspx). Just extract the ZIP file you download and double-click Autoruns.exe to run it. Like Msconfig, each checked entry is set to run automatically at startup, and unchecking a program disables

it at startup. (You’ll still be able to use program but will have to manually start it each time.) AutoRuns is more thorough in ferreting out auto-start programs, so its list is much longer than Msconfig’s and broken down into different auto-start methods. To whittle that list and focus on third-party software, click Options, Hide Microsoft Entries, and the Refresh button. Regardless of which utility you choose, you shouldn’t just uncheck everything in the list. (Although interestingly, WinXP will run just fine— and quite fast—with everything disabled in the Msconfig Startup tab). Instead, you need to figure out what each item is and decide if it’s something that you really need to run every time Windows starts. For example, many peripherals, such as PDAs and game controllers, have supporting programs that start automatically every time (you can usually see their icons in the System Tray), but how often do you really HotSync your Treo or play a game? If you don’t frequently use the peripherals that require these support applications, consider disabling them at startup. When you plan to actually use the device, manually run the program instead. For example, only run the PalmHotSync Manager when you actually need to HotSync your PDA. You should only disable programs that you can properly identify; determining which programs you can disable occasionally requires some sleuthing. For example, you can track down an oddly named program, such as P17Helper, by doing an Internet keyword search. In this particular case, P17Helper is an ASIO (audio stream input output) driver for a Sound Blaster card, which allows for high-speed digital audio recording. If you never record digital audio, you should consider disabling it. Many Web sites that identify startup programs also state if you can safely disable the programs. Deciding what to disable can be tricky if you can’t find guidance online, but there are useful guidelines the adventurous can follow. If you disable a program related to hardware, reboot and see if the hardware still works. If it doesn’t, re-enable the program. Ditto for software application helpers—make sure the main application they help still runs after you restart. Many programs, such as Microsoft Office, Adobe Acrobat, and RealPlayer, preload some parts of an application into your system’s memory under the assumption that the associated applications will start a few seconds faster when you actually run them. You can safely disable these preloaders, but the trade-off is that your application might take a few extra seconds to load. Some applications install their own schedulers or version checkers, which is something you can usually do manually. Don’t forget to check for updates yourself if you disable these programs at startup. Ideally, when you identify a startup program you want to disable, you should disable it from within the program itself. If there’s no such option, simply uncheck its entry in Msconfig or AutoRuns.

How To Deal With PC With Virus

2009-09-09T22:42:00.003Z

Whether you suspect that a virus is causing your PC to behave oddly or your antivirus software finds a bug lurking on your computer, it’s hard to think about anything else until you’ve removed the virus. Because your computer isn’t healthy, your valuable documents, music and video files, and email are at risk.

In theory, removing a virus should be easy: Run your antivirus software’s virus scanner until it locates the bug and then zap it. Although antivirus programs can indeed catch and kill many of the viruses that find their way to your PC from the Web, there are plenty of elusive bugs that can evade your antivirus software for one reason or another. We’ll show you how to use two popular antivirus applications to catch and kill viruses, and we’ll also provide tips for removing the bugs that refuse to budge.

Step 1Back Up,

Back Up, Back Up

If your PC has any files you don’t want to lose, resist the temptation to hunt for that virus right away. Although your antivirus software may be able to remove the problem without disturbing your OS (operating system), you can’t predict the sorts of trouble you may run into. This is an especially important step if you haven’t yet installed antivirus software. Although most program installations go smoothly, we’ve experienced more than our fair share of software and hardware installations that crippled our test PCs’ operating systems. Back up your files to a CD, DVD, or other removable media—not to another PC. Some viruses infect documents and other popular file types, which means that your own files may carry the virus to the removable media. You’ll need to scan your backup media with an antivirus program before you return the files to your computer or move them to another PC.

Step 2Update Your Virus

Definitions

Antivirus software publishers create massive databases of virus definitions that help your software identify the bugs. Because malicious users regularly create new viruses (and publishers regularly create new virus definitions to catch them), your antivirus software is out of date as soon as you install it. You’ll need to download the latest definitions from the software publisher before you run your antivirus scan—otherwise, the program may miss a new virus. Many antivirus applications include a 12-month subscription to the publisher’s antivirus definitions; if your subscription has expired, the software may instruct you to pay for a new subscription.

Step 3Scan Your Computer

When you run a virus scan, your antivirus software scours your computer in search of files that match its virus definitions. You don’t need to sit by your computer as it scans: It will identify viruses and display a report once it completes the scan.

Step 4Remove The Virus

Today’s software makes removing most threats a breeze. Many applications can automatically remove minor threats or suggest removal actions.

Online Resources

Don’t panic if you think you have a virus but don’t already have antivirus software. Some antivirus software publishers offer free online scanning tools that can search your computer in minutes. McAfee, for example, offers McAfee FreeScan (us.mcafee.com

/root/mfs/default.asp) and Symantec also has a Spyware & Viruses scan (www.symantec.com/home_home office/support/index_virus.jsp). You can also use these tools if you think your existing antivirus software hasn’t caught a virus on your PC.

Some lesser-known publishers also offer online scanners. If you choose to use a scanner you don’t recognize, search the Web for other users’ opinions.

Malicious users can create legitimate- looking security programs that “find” phantom viruses and ask you to pay for the software to remove it.

Once you know the name of your PC’s virus, you can search for information about removing it. Some software publishers offer special, downloadable tools for nasty viruses. In some cases, you’ll need to install a full antivirus program to destroy the virus.

Viruses vs. Adware & Spyware

Many antivirus applications don’t search for adware and spyware. If you’ve run antivirus scanners without any luck, the program that’s causing your computer to behave oddly may fall into the adware or spyware category. Several security publishers offer free antispyware/ adware programs such as Lavasoft’s Ad-Aware SE Personal (www.lavasoft

usa.com) and Grisoft’s AVG Anti-Virus Free (free.grisoft.com).If your antivirus and other apps fail to remove your PC of its malady, it may be time to wipe the system clean and reinstall your OS. Be sure that once your fresh OS is installed, you update

Windows completely and install your antivirus software before you reintroduce your backed up files to your PC. After all, they may still carry viruses.

A Continually Restarting PC

2009-09-07T10:18:00.001Z

The continuous reboot problem can have a variety of causes, including faulty or unseated memory modules; out-of-date, corrupt, or missing drivers; software conflicts; overheating components; virus or malware; bad software; or bad hardware.

Hardware

Your computer may immediately fail to boot if one of your memory modules is unseated. The memory modules are long, narrow sticks that attach to the motherboard located near the processor and have clips at either end. If one or both of the clips is not closed or laying flat against the edges of the module, press down on the edge of the nearest to the clip. You may have to remove the memory module and reseat it. Restart the computer. Your computer may also immediately reboot if another piece of hardware fails, has a loose connection, or becomes disconnected. Check that power plugs from your power supply are connected to the appropriate components and that those connections are secure. Listen for your hard drive to start spinning. If it is silent, then it may be faulty or disconnected from the motherboard. Also, be sure the fans on your motherboard or graphics card start spinning. If any component seems unresponsive, replace it.

BIOS

If the settings in the BIOS have changed or become unstable, you may need to reset the settings to get your system to boot again. Restart your computer and access the BIOS setup utility. When you have access to the BIOS setup utility, you should see options to Load Defaults, Load Optimized Defaults, Load Fail-Safe Defaults, or something similar. First, try loading the Optimized Defaults. If your computer still fails, re-enter the BIOS and load the Fail-Safe Defaults. If you don’t have a choice, simply load the default settings as described in your computer or motherboard manual. Confirm your choice and allow the system to reboot. You may have to select the Save And Exit option to restart your system.

Sometimes, your computer won’t even let you access the BIOS. In these instances, you may have to reset the BIOS using a more hands-on approach. The CMOS (complementary metal-oxide semiconductor) memory retains your computer’s BIOS settings but can be reset by moving a jumper on a three-pin header on the motherboard and then moving it back to its original position after a short wait. You’ll have to consult your computer or motherboard manual for specific instructions on how to perform this operation. Restart the computer.

Reseat your memory modules one side at a time.

Restarting sans error message

If your system is infected with a virus or malware or experiencing system-crippling errors, you may never see error messages that can provide clues as to why your computer continuously reboots. Windows is set to reboot when it encounters a critical error. Disabling this can let you view error messages and on-screen prompts.

If you can boot into Safe Mode, disable unnecessary

startup programs that may be breaking Windows’ bootup

To change the setting in WinXP, boot into Safe Mode and access the Control Panel. If you’re using Win2000/XP with the Control Panel displayed in Classic View, simply double-click the System icon. If you’re a WinXP user viewing the Control Panel in Category View, click Performance And Maintenance and click System from the bottom of the dialog box. Click the Advanced tab and then click the Settings button from the Startup And Recovery section of the System Properties dialog box. Next, deselect the checkbox in front of Automatically Restart in the System Failure portion of the dialog box. Click OK and click OK again. Close the Control Panel and restart the computer. Now, when your system encounters an error, it will remain on-screen.

Whatever the circumstances surrounding a particular boot failure, the important thing is to address the issue immediately.

Follow the steps we’ve described here, refer to the product documentation that came with your computer, and contact the computer manufacturer’s support resources for step-by-step guidance in resolving the problem. And take heart: You will get your PC up and running again.

Error Messages After Windows Starts

2009-09-07T09:28:00.001Z

When Windows launches but won’t go any further without locking up or spewing forth error messages, check out the following options.

Windows utilities

Repeatedly press F8 (check your PC’s documentation for another option if this key doesn’t work) during startup to launch the Windows Advanced Options menu. Select Enable Boot Logging. When Windows starts, go to C:\WINDOWS, open Ntbtlog.txt, and browse for error messages. Work from Safe Mode to repair any errors you find.

Safe Mode

Select Safe Mode from the Windows Advanced Options menu. Safe Mode loads Windows with a minimal set of drives and processes for more effective troubleshooting. Perform some basic system maintenance, such as an antivirus scan and Chkdsk. Reboot your computer. If this fails to solve the problem, go back to Safe Mode and use Add/Remove Programs to uninstall anything you recently added to your system. Also try a System Restore, which will roll the OS (operating system) back to its state at an earlier date. Go to Start, All Programs, and Accessories. Select System Restore from the System tools submenu and follow the prompts.

Last Known Good Configuration

If you can’t perform a System Restore from Safe Mode, select Last Known Good Configuration from the Advanced Options menu. Last Known Good Configuration rolls back your Registry and device drivers to the last setting under which your computer shut down successfully.

Windows CD

Use your Windows installation disc or system recovery CD. Insert the disc and boot up. You need to press any key in order to boot from the disc. If not, you’ll have to enter the BIOS and set your optical drive as the primary boot option. After setting the optical drive as the primary boot drive, restart your system and try booting into Windows. There’s a difference between a true Windows OS disc and the image restoration discs many manufacturers ship with PCs. If you only have the latter, the following tips may not work. Windows’ repair option attempts to re-create the Registry and restore settings without removing or altering user data. When a repair is available and works as planned, it’s a great way to get a troubled system running again without starting from scratch. Boot into your Windows installation disc or system recovery CD. When prompted to choose between setting up Windows, accessing the

Recovery Console, or quitting Setup, press ENTER to enter Windows Setup. Press F8 to accept Microsoft’s license agreements and then press R to Repair the selected

Windows installation when prompted.

Recovery console

If you have any way to back up your data, do so. Boot from your Windows installation CD (a manufacturer’s restoration CD won’t work). Press R from the Welcome screen. Select your Windows installation if prompted and enter your administrator password. At the command line, delete your existing Registry files by typing delete c:\windows\system32\config\system. Repeat four times, substituting software, sam, security, and default for system, each in turn. Now copy pristine versions of those files by entering copy c:\windows\repair\system c:\windows\system 32\config\system. Repeat four times replacing system in both portions of the command with the words software, sam, security, and default. Type exit, press ENTER, and reboot.

A Beeping Computer

2009-09-07T08:32:00.000Z

Should something go wrong during the boot process that prevents the computer from even sending data to the monitor or starting the computer, you need some way to identify the problem. When something goes wrong that causes the BIOS to be unable to start the computer properly, it uses specific patterns of beeps to give you clues to what the underlying problem is.

New hardware. It’s easy to accidentally bump something while working inside a computer. Retrace your steps and ensure everything is firmly in place. Reboot your computer. If the beeping continues, remove the new hardware and see if the beeping goes away.

Beep codes. There aren’t any standard beep patterns. To make sense of the beeps, you first need to identify your BIOS. The documentation for your motherboard likely contains this information. With this data in hand, search online for the meanings behind the beeps. Many sites offer such information.

Defective components. If your problem persists, it’s time to look at replacing the troublesome component. If your beep codes indicate that the RAM is failing, you might need to first figure out which module in particular is the problem, because most computers have more than one memory module installed. Depending on how old the computer is, you should be able to take out the memory modules one at a time and reboot the computer to see if the problem goes away; doing so will identify the problematic stick of RAM. If your video card is the problem, swap it out with a new one and see if the problem continues. Make sure that the video card you choose to troubleshoot or replace yours with is compatible with your motherboard and your operating system— otherwise, you will only create new problems.

For troubleshooting purposes, it is helpful to have another computer you can borrow parts from. It is best to work through the troubleshooting and be fairly confident of your diagnosis before you run down to the local computer retailer and start buying replacements. If the new parts don’t fix the problem, you may be stuck with parts you can’t return.

Error Messages Prior To Windows

2009-09-07T05:24:00.000Z

Dealing with a PC that seems to be starting up but stops and coughs up an error message before it can load Windows is one of the more frustrating situations a computer user can experience. Fortunately, these messages do have a rhyme and reason. Often (but not always), they indicate a minor problem.

Easy fixes. If an error message offers Last Known Good Configuration or Safe Mode, the error has something to do with Windows’ startup. Selecting the former option can solve a world of unknown ills. The latter is a good choice if you’ve recently added new hardware. Make sure there isn’t any removable media, including floppy diskettes, CDs, and thumb drives, in any drive. If you see an error message regarding keyboards, it’s most likely the cable has come loose. Barring that, make sure none of the keys are stuck and that all of the pins in the connectors are straight. If it’s still malfunctioning, try a new keyboard—most models are quite inexpensive.

Memory and parity errors. These error messages indicate problems with your PC’s memory modules. Remove memory modules and carefully reseat them in another slot. If the computer restarts properly, the slot is likely to blame; if it doesn’t, it’s likely the memory itself is the problem.

Unexpected Interrupt In Protected

Mode. This is indicative of an incompatible change to your BIOS (Basic Input/Output System). Enter your BIOS setup menu and look for an option to reset the BIOS to its defaults.

NTLDR missing. NTLDR (think NT Loader) is the first file that executes during the boot process; it can get moved, accidentally deleted, or corrupted. Restore NTLDR from the Windows XP Setup CD via the Recovery Console. At the command prompt, type cd.. and press ENTER. Enter the letter of your CD-ROM drive (probably D:, unless you have multiple drives) and press ENTER.

Type cd i386 and press ENTER. Type

copy ntldr c: and press ENTER. Type

copy ntdetect.com c: and press ENTER. (Ntdetect.com is another boot file that, when missing, can generate the NTLDR error.)

After the copy process completes,

type Exit and press ENTER. Your computer will restart.

What to Do If Your Computer Won’t Start

2009-09-05T14:50:00.001Z

What to Do

When we press the power button on a computer, we expect that the operating system will appear on-screen. And when the expected does not happen, we . . . well, some of us freeze, some of us panic, and some of us gather our wits and prepare to fix the problem. The first step in restoring an expectation is to figure out specifically what went wrong. It’s not enough to say the lights won’t work or the car won’t start or the computer is on the blink. We have to determine whether a light bulb has burned out or a fuse is blown, whether we’re out of gas or the battery is dead, whether a cord is unplugged or the hard drive has crashed. Fortunately, making this kind of determination is rather simple, even when it involves a PC.

Finding the specific cause of a failed boot involves some detective work. Take note of everything that happens during the failed boot from the moment you press the power button to the moment the boot routine grinds to a sudden halt. Write these details, including the full text of any error messages you see, on

a piece of paper so that you can refer to them later.

No Power at All

As grave as this may seem at first blush, a computer that refuses to start isn’t usually all that serious. Oftentimes, something outside the computer itself is to blame for a powerless computer.

Power cord. A loose power cord is usually the problem that prevents your computer from starting.

Check each end of the cord to make sure it’s firmly in place. Also be sure to check the cables that run to your monitor.

Some power supplies have switches that let you

cut power to your system. Make sure you haven’t

turned off your power supply.

Power supply switch. See if your computer’s power supply has an on/off switch that lets you kill

power to the PC without removing the cable. This button, located on the back of your computer, can get accidentally bumped.

Surge protectors, outlets, and fuses. Make sure the surge protector is firmly plugged into the wall outlet and that the power button on the surge protector is in the on position. If that checks out, see if the devices plugged into other outlets on the power strip are functioning. If not, the surge protector might be to blame.

Another likely culprit is a faulty wall outlet. Plug your computer directly into the outlet, sans surge protector. Ensure that the GFCI (ground fault circuit interrupter) hasn’t been tripped. If your PC still won’t turn on, plug something else, such as a lamp, into the socket to see if it works. Finally, check your fuse box or circuit breaker to make sure there isn’t a blown fuse or tripped circuit.

There are also a number of factors inside the computer that could prevent it from starting.

Motherboards and power supplies.

Most motherboards have a tiny light on them that lights up when the power supply is connected, even if the PC is off. If this LED (light-emitting diode) is lit, your PC is getting power, and your problem lies elsewhere. Power supplies can sometimes go bad, and if you’ve followed our troubleshooting steps to this point, you may have a dead PSU (power supply unit). To figure out whether this is the case, use a power supply tester. Follow the manufacturer’s instructions to check the well-being of your PSU.

Power button cables. If you’ve recently performed any repairs to your system, it’s quite possible that you accidentally pulled the power button cable free from the motherboard. If you spot an unplugged cable, check your motherboard for labels that indicate the prongs that support the power switch. In the event there are no such labels, check your motherboard’s users manual

How to Deal with Error Messages

2009-09-04T16:30:00.000Z

When you were kid, you imagined that the future held flying cars and moon bases. Technology and humanity would be in perfect sync. Our machines would anticipate our needs, leaving us to pursue only the most relevant, important work. Well, it hasn’t happened yet; we’re still very much slaves to our machines instead of the other way around. It sometimes seems we can’t go an hour without intercepting some bad news from our computers: missing drivers, no paper in the printer, an exception at memory address 32xxff00. . . . Can’t we just get our work done? Don’t go back to pen and paper just yet. I’ve got some tips to help you deal with the different kinds of errors you run into while working with your PC.

An Error For Every Season

Error messages are communications from the PC to you. To create one, a programmer must anticipate an action you might take with which the system will disagree or by which the system will become confused.

Depending on how well the software is designed, these messages may either be informative or—so it sometimes seems—deliberately obtuse. There are hardware errors, software errors, and user errors.

Trying to answer these messages that associate the errors, one must have answers in a form like:

1. What is the problem?

2. Why is it a problem?

3. What can I do to solve the problem?

For a good example, consider a common type of user error: those related to printing. A good error message would inform you that your printer is out of paper that you won’t be able to print unless you load more paper into the tray, and that you should click

Print after you have loaded it. If you’re a user who often feels a victim of your computer, you can rest assured that if you see an error message that doesn’t meet these criteria, the programmer is almost certainly the one at fault, not you.

The Blue Screen of Death

Most hated error message, the Blue Screen Of Death

providesinformation that can help developers

track the cause of an error.

The most infamous error message is the Blue Screen Of Death. It’s so well-known that it has crept into the vernacular: “Aw, man! I was almost finished with my term paper when I got bluescreened!” The phenomenon is also known by its acronym, BSOD.

The conditions that cause a blue screen have changed since the days of Windows 95/98, as has what it means. In either case, chances are pretty

good that, if you get bluescreened, any unsaved work will be lost, as either Windows (in NT/2000/XP) or your application (in 95/98) has been shut down. The BSOD is perhaps the most despised error not only because it has wiped away countless hours of work over the years, but because of the obtuse way in which it does so. The messages delivered in the typical blue screen are meant for developers more than end users. For example, a blue screen delivered by Windows may deliver a message such as the following:“0x0000001E, KMODE_EXCEPTION_NOT_HANDLED.” And if you don’t find that sufficiently informative, you’ll see four variables in parentheses to help developers figure out what’s happening. Again, none of this will mean much to most of us, but a support rep or developer can often learn a great deal from such cryptic messages. Fortunately, blue screens are rare in recent versions of Windows and may disappear after a reboot. But if the problem recurs, you could have a real problem. Here are some troubleshooting steps to follow if you encounter a BSOD: While your system is booting, press F8 and select Safe Boot Mode, which loads a subset of Windows with minimal drivers. If things run smoothly in Safe Mode, you likely have a software problem with a recently installed application.

Try to decipher the error message to see if you can trace it to a specific program. If all else fails, uninstall your most recently-installed application. If you still see blue screen errors in Safe Mode, restart again and use F8 to get to the advanced options. This time, choose Restore Last Known Good Configuration, which is a snapshot of your system as it existed before you last installed any drivers or other software. You will lose any system changes you’ve made since that point, but your documents will normally remain untouched by this process. If you’re still having problems, you are likely suffering from a hardware problem or a corruption of vital system files. Again, any hints that you can glean from the error message could help you (or a tech support rep) trace the source of the problem. Remove any recently installed hardware and try booting again. In the worst case, it’s not uncommon to have to resort to reinstalling device drivers or even the whole operating system. Ultimately, the best cure for the BSOD is prevention: Save often, create frequent backups, and burn a little anger to curry favor with variable PC spirits.

How to Fix Your Own Computer

PCs are wonderful tools that occasionally refuse to work the way they should. When something does go wrong, you can avoid frustrating and costly by learning to fix your own PC. Use the basic troubleshooting techniques and step-by step instructions in this website to solve hundreds of common hardware and software problems.

Trace the source of the problem

As the days goes by, PCs continue to increase in complication and our reliance with time.

People across the globe turn their PCs on each day to use them for research, leisure, entertainment learning, etc. Since we rely on the PCs to do our day to day activities, so there is equally needs for maintenance to avoid break down, cost, frustration especially when the PC just doesn’t work, and we don’t know why. The process of restoring the computer back to standard state is called troubleshooting, this process diagnosis the computer to get it back on the right truck

Although it’s tempting to start troubleshooting your computer as soon as it displays symptoms, you’ll save yourself a potential headache if you back up your files or document on a removable media like, pen drive, etc. so u can do away with the fear of losing your data.

It’s not always easy to determine whether your hardware or software is to blame, but it’s a good place to start troubleshooting: If you’re fairly confident that the problem is one or the other, you’ve eliminated several troubleshooting steps.

Look for common hardware symptoms.

Hardware problems, such as damaged components or loose cables, generally cause obvious, dramatic problems. For example, if your computer won’t power on at all, you’re looking at a hardware problem, rather than software. You should also suspect a hardware problem if your computer powers on, but no images appear on your monitor. If you can’t access any software (even the BIOS [Basic Input/Output System]), you’re not looking at a software issue. Of course, not all hardware issues display such obvious symptoms, and some hardware problems exhibit symptoms similar to those caused by software problems. For example, if your PC runs slowly, it may have too many unnecessary programs running at once or a virus or adware may be crippling your system; obviously, these are software problems. On the other hand, these same symptoms can be caused by an overheated processor, something that’s just as obviously a hardware issue.

Look for common software symptoms

A conflict between two programs, for example, may prevent you from accessing certain applications, but may not crash Windows itself. In many cases, the software that’s experiencing trouble will display an error message. Unfortunately, many error messages don’t offer much immediate help: The message will likely display a cryptic warning or a bunch of numbers and letters that don’t mean anything to anyone other than a programmer. Unless you receive an error message saying that hardware is to blame, the error message is a good indicator that you’re facing a software problem.

Find The Source Of The Problem

Once you know (or think you know) whether you’re dealing with a hardware or software problem, you can really dig into the next question: Which hardware component or program is the source of the trouble? If you can answer this question, you won’t have any trouble finding an article in this issue that addresses your problem. Here are some tips for narrowing the troubleshooting field.

Hardware problems.

Once you suspect a hardware problem, list the components (internal or external) that might be the cause of the problem and then check each component, one at a time. In some cases, this may mean checking external and internal hardware. For example, if your print documents don’t reach the printer or you see error messages that say your printer isn’t connected to the computer, you’ll want to check the USB cable that runs from your computer to the printer to make sure neither of the connections is loose. You’ll also want to be sure that your computer’s USB port is functioning. (You can test this by plugging another USB device, such as a USB flash drive, mouse, or external hard drive into that port.).

In some cases, you may suspect that an internal component is damaged, but not be in a position to confirm the defect. If you think that your computer’s lost network connection is due to a damaged or incorrectly configured Ethernet NIC (Network Interface Card), you probably don’t have an extra Ethernet card that you can swap out. This is where the Device Manager, a built-in Windows tool, can help you identify problems without opening your PC or bumming spare parts from your friends.

To open the Device Manager, right-click the My Computer icon on the Desktop, and then click Properties. When the System Properties window appears, select the Hardware tab and then click the Device Manager Button. The Device Manager displays a list of your PC’s components by category, such as Disk Drives (hard drives),

The Device Manager lets you quickly determine whether your PC’s components are working properly. A red X indicates a problem.

Processors, DVD/CD-ROM Drive, and Display Adapters. By default, the list shows only the component categories, rather than the components themselves. If you want to see the names of your specific CD-RW and DVD-RW drives, for example, you’ll need to click the plus (+) sign next to DVD/CD-ROM Drives. The list will then expand to reveal all of the components in that category

Things to Check First

Although a list of things to check won’t catch every PC problem you encounter, you’ll be surprised at how often the simple steps below can lead to troubleshooting success. Whether you’re kicking off a troubleshooting session or at your wits’ end after hours of fruitless research, here are some good tips to try. Is the PC’s power supply switch turned on? Some PCs have a power switch at

the back. Make sure it hasn’t been switched off.

Are all cables connected? Loose connections regularly cause headaches. Remove and reconnect each plug firmly, even if you’re sure it’s connected.

Are all peripherals turned on? Make sure a powered-off print server isn’t preventing your printer from working.

Does the Device Manager display any problems? Check this tool for red Xs,

Which indicate a malfunctioning or disabled device?

Is there a new driver? Updated drivers often fix hardware problems. If you can’t find new drivers (check the manufacturer’s Web site), try reinstalling your existing driver.

Have you installed software updates? Software publishers sometimes release

patches via their Web sites. Also, check to see if your software recently installed

updates automatically. In rare cases, a software update may introduce problems.

Software problems.

If you’re fairly certain you’re facing a software problem, but you haven’t been able to identify the offending program, your best bet may be to use Windows XP’s System Restore. This feature is especially useful if you’ve installed multiple programs recently. System Restore reverts your computer to the condition it was in few days or even a few weeks ago, without destroying any of the documents, emails, music, or video files you’ve created. Thanks to System Restore, any programs you installed after the Restore Point (the date in the past to which you restore Windows) won’t appear on your PC. Once you complete the restore, you can reinstall the applications

one at a time and check your PC for problems after each installation.

System Restore is enabled by default in Windows XP, which means

that System Restore has already created Restore Points automatically, even if you’ve never used the System Restore feature before. To access System Restore, click Start, All Programs, Accessories, System Tools, and System Restore. Once you click the Restore My Computer to an Earlier Time radio button and click Next, System Restore will display a small calendar with several of the dates in bold. All bold dates have at least one Restore Point. (Note that Windows refers to automatically created Restore Points as System Checkpoints; you can create your own labels for Restore Points that you create yourself.) Select the Restore Point and then follow System Restore’s instructions to restore your system to this earlier date. Finally, make sure your PC is operating without trouble. If it is, you’ve narrowed the problem to one of the programs that System Restore just uninstalled (or to another program on your PC that conflicted with one of these programs). Now you’re ready to hunt for the problem program.

Troubleshooting

As we mentioned earlier, troubleshooting is largely a matter of eliminating parts or programs that are working until you find the part that causes the problem. Consider this scenario: You pressed your PC’s power button this morning only to find that it didn’t start. The PC worked just fine last night, and you haven’t recently performed any maintenance on the system’s interior. If you start by making sure your PC truly isn’t powered on, you’ll save yourself several troubleshooting steps. Check the monitor’s light: Is the monitor on? If not, you’ll want to check its power cords. Once the monitor is on, take a second look at your PC. Do any lights appear when you try to power on the system? If you see lights, or if you can see or hear running fans at the back of the computer, the system doesn’t have a power problem. Instead, the PC may be having trouble sending an image to your monitor, which could indicate a problem with your motherboard, video card, or memory. If the PC doesn’t power on at all, check the power cord and the surge protector. Many surge protectors have switches that let you kill power to any of the devices that plug into them: Check to make sure your pet didn’t accidentally trip that switch. Next, check the wall outlet by plugging a different device into the socket your PC’s power cord occupied.,
