your error message in your search. You ll do well to type the letters XPas thefirst word of your search text, to try to narrow the search to Windows XPissues. If the error message is related to printing, check out www.microsoft. com/insider/printhelpfor possible solutions. Still, there s no guarantee that you ll find your exact error message and simplesolution. Sad but true sometimes you just need to know what you re doing. There is no single book, or single Web site, that contains everythingthere is toknow, let alone a solution to every problem. But the better you re able tosearch for information when you need it, the more likely you ll be able to solve the problem quickly. If Windows XP came preinstalled on your computer, your manufacturer sWeb site can also be a great resource for information. If you don t know theURL, try sticking the company name between www. and .com, as dell.com, www.gateway.com, www.hp.com, www.SystemMax. com, and so forth. There s an old saying about knowledge being of two kinds: the things wealready know and the things we can find when we need it. Knowing how to usethe Help and Support Center is critical to getting the information you need, when you need it. Easy TroubleshootingWindows XP has some built-in troubleshooters that can help you diagnose andsolve many problems on your own. To get to the troubleshooters: 1.Click the Start button and choose Help and Support. 2.Click Fixing a Problem (if you see it). The left column of the Help and Support Center will list many different types as shown Figure 26-2. Use the scroll bar at the right side of the listto see all of your options; then click whichever option best describes yourproblem. Finally, click a specific option in the right pane. Some computer manufacturers replace the built-in Help and Support Centerwith their own version. If you don t see Fixing a Problem as an option on thefirst page of your Help screen, there s another way to get to them. In the Searchbox near the top of the Help window, type List of troubleshooters, andpress Enter or click the Start Searching button just to the right. Then click Listof troubleshootersunder Suggested Topics, as shown in Figure 26-3. Scrollthrough the list of troubleshooters, and click whichever one best describes theproblem you re experiencing.

with them is as follows. First of all, read the message. That may seem obvious, but a lot of people just close these little message boxes without reading themfirst. Bad idea! The message appears for a reason: to tell you what went wrong. Figure 26-1:A sample error messageIf the message makes no sense to you, there are a few ways you can get moreinformation. .Some (but not all) error messages contain a Help button, which youcan click to get more information about the problem. .If you were trying to accomplish something by guessing, considerusing Windows Help and Support to look up a better way to do the job. .If there are specific technical terms in the message that you don tunderstand, consider looking up those terms in Windows Help andSupport. The Windows Help and Support Center provides help for Windows only. Just about every program you use will have its own, separate help, whichyou can get to by choosing Help from that program s menu bar. SeeChapter 3 for more information on Help and Support. For example, the error message in Figure 26-1 says there was an error copyingthe file but offers no Help button. A good strategy there would be to openWindows Help and Support, search for the phrase copy file, and learn aboutdifferent ways to copy files. Maybe you can figure out what you did wrong byreading the Help. The problem in Figure 26-1 is that I tried to copy a folder to itself, whichdoesn t really make sense. As discussed in Chapter 19, the term sourcerefers to the thing you re copying, and the term destinationrefers to theplace to which you re copying the item. If you try to get around the error my doing exactly what you did to create theerror message in the first place, guess what? You ll see the exact same errormessage again. If the Help and Support Center is no help, you can break out the big guns andgo to http://search.microsoft.com. That Web site contains mountains ofinformation.

2626CHAPTERDisasterPreventionand RecoveryComputer problems will occur, especially if you re abeginner trying to figure things out as you goalong. Fortunately, most of these problems are trivial, resulting in no more than descriptive error messages on the screen and a button to get back to where you left off. Some problems can be a bit more serious. We some- times refer to the bigger problems as fatal errors. Theword fatalis a bit extreme though. Using a human anal- ogy, I think it would be more accurate to say temporarilyunconsciousrather than fatal. Then again, there are big problems, like hard diskcrashes that cause you to lose all or most of the con- tents of your hard disk. These are extremely rare, how- ever. But it certainly can t hurt to keep backup copies ofimportant files, just in case. In this chapter, you ll learnstrategies for dealing will all types of problems, fromsmall to large. Dealing with Error MessagesThere are lots of little things that can go wrong whenusing a computer, especially for beginners who are try- ing to do and learn at the same time (or are skipping thelearn part altogether). When little things go wrong, you ll see some sort of error message on the screen. There are tons of little error messages for differenttypes of errors. Figure 26-1 shows an example of one. Unfortunately, error messages don t go to great lengthsto explain things. Error messages use all the officialbuzzwords of the computer biz, which is like Greek (orgeek) to the neophyte.

Figure 25-9:The Windows XP Device Manager5.Choose Action.Uninstall from the menu bar in Device Manager, orclick the Uninstall button in the toolbar. 6.Read and follow any instructions on the screen to completion. 7.Close all open dialog boxes and windows. 8.Click the Start button and choose Turn Off Computer.Turn Off. 9.When the computer shuts down, disconnect the device from thecomputer. 10.Turn the computer back on. The computer should boot up normally to the Windows desktop. If you set arestore point prior to installing the hardware you just removed, see the section”Restoring Your System Files,” later in this chapter, to go back to your previousrestore point. Restoring Your System FilesIf you set a restore point just before installing a new program or hardwaredevice, then changed your mind and uninstalled that program or device, youcan go the extra step and restore all your system files to their previous state. Make sure you uninstall the program or hardware device first. Then followthese steps to restore your system files to the most recent restore point: Never use System Restore as an alternative to a simple Undo (Ctrl+Z). Restoring your system files to an earlier time undoes all changes thatyou’ve made to your system since setting the restore point. If you installedany new hardware or software since that time, restoring your system filesis likely to create a lot more problems than it solves!

Figure 25-8:The Safely Remove Hardware dialog box If you see the name of the device you’re about to remove, clickits name and choose Stop. Click OK in the Stop a HardwareDevice dialog box that opens. If you don’t see the name of the device you’re about to remove, don’t worry about it. It just means there aren’t any open files, sothe device need not be stopped. 3.Click the Close button in the Safely Remove Hardware dialog box. Now you can turn off the USB device and unplug the cable. Uninstalling Other Types of HardwareHardware devices that don’t connect through a USB or FireWire port are a littlemore complicated to remove. Once you uninstall a device, you won’t be able touse it again unless you reinstall it from scratch. So don’t uninstall any hardwaredevices just for practice. Know what you’re removing, and why, before you doanything. Then do the following: STEPS:Remove a Non-USB Hardware Device1.Close all open program windows. 2.Right-click the My Computer icon on your desktop or Start menu andchoose Properties. The System Properties dialog box opens. 3.Click the Hardware tab in System Properties; then click the DeviceManager button. 4.Click the +sign next to the icon that represents the type of deviceyou’re about to remove; then click the name of the specific deviceyou want to remove, as in the example shown in Figure 25-9.

If you see a message indicating that some of the files to bedeleted might be shared with other programs, you can choosewhichever option allows you to keep those files on the computer. They’re tiny files that don’t take up much space and will do noharm in left in place. 6.Close the Add or Remove Programs window and Control Panel. The program has been removed from your computer, and its icon(s) removedfrom your All Programs menu. If you removed this program because it madeyour computer unstable, and you set a restore point before installing the pro- gram, see the section “Restoring Your System Files,” later in this chapter, to goback to your previous restore point. If you see a bunch of Windows XP Hotfix programs in the Add or RemovePrograms window, those are security patches that have been downloadedautomatically from the Windows Update Web site. Leave those in place. They make your computer more secure. Uninstalling HardwareUninstalling (removing) hardware is easy for USB devices a bit more compli- cated for other types of hardware. But either way, you generally want to tellWindows you’re about to remove the device before you actually remove it. Doing so gives Windows a chance to reconfigure your system to operate correctly without that hardware device. Removing USB DevicesCertain types of USB devices, such as digital cameras and disk drives, transferfiles back and forth to your computer. It’s always a good idea to make sure anyopen files are closed before you disconnect the device, so you don’t end upwith any corrupted files. Here’s how it works: STEPS:Remove a USB Device1.Look for a Safely Remove Hardware icon in the notification area, as inthe example shown in Figure 25-7 (the tooltip appears when you’repointing to the correct icon). Figure 25-7:Notification area icon forremoving USB devices2.Double-click the notification icon to open the Safely RemoveHardware dialog box shown in Figure 25-8. Then . . .572Part

changes to your system that need to be unchanged to get your computer backto its previous state. The terms uninstalland removemean to get rid of permanently. If youthink there’s even an outside chance you’ll use the program again, don’tremove it.

You should see a message, or a series of messages, pop up near the notifica- tion area. When you see a message telling you that the product is installed andready to use, as in the example in Figure 25-5, you’re done. The product isready to use. Figure 25-5:Connected USB device installed and ready to useInstalling Non-USB DevicesHardware devices that don’t plug into a USB (or FireWire) port are not hot- pluggable,which means that the computer must be turned off when you connectthe device. Again, I strongly encourage you to follow the device manufacturer’sinstallation instructions. But in general, the procedure goes like this: 1.Close all open programs and save any work in progress. 2.Shut down windows (click the Start button and choose Turn OffComputer.Turn Off). 3.If your computer doesn’t shut down all the way, turn the computeroff using its main power switch. 4.If your device needs to be plugged into a wall socket, go ahead andplug it in. 5.Connect the device to the computer via the appropriate cable. 6.Turn the hardware device on. 7.Turn the computer on last. As Windows is booting up, it should detect the device. If Windows needs moreinformation or files, you’ll see instructions on the screen. Follow those instruc- tions, and the device should be ready to use by the time you get to theWindows desktop. Uninstalling ProgramsIf you have any old programs that you don’t use any more and want to free up the disk space that the program is using, you can uninstallthe program. Likewise, if the newly installed program is causing your computer to misbehave, you can uninstall it; then use System Restore to bring back your previous system files. Keep in mind that it’s never sufficient or safe to just delete the program’s iconsor files from your hard disk. When you install a program, it makes certain570Part
