Top of page Before You Try System RestoreSystemRestore should only be used after trying less comprehensive methods oftroubleshooting. System Restore changes many files and registryentries, and in some cases might replace more files than you wantrestored. So when I first run into a computer problem, I reboot mycomputer. I'm still amazed at how often a problem is solved by usingthis simple technique. Or, if your computer won't start in normal mode,reboot your computer, press F8 during the boot process, use the arrowkeys to highlight Last Known Good Configuration, and then press ENTER.
Other troubleshooting techniques that often work are listed below.
Run problem applications in Compatibility Mode if system instability occurs after installing a particular application. To run the Program Compatibility Wizard:
• Click Start, point to All Programs, point to Accessories, and then click Program Compatibility Wizard.
Use Add or Remove Programsto uninstall a problem application if the system instability hasoccurred immediately after a new application has been installed andrunning the program in Compatibility Mode hasn't helped. AlthoughSystem Restore will remove the application if you choose to apply it,it is better to remove the offending application from Control Panel. Toopen Add or Remove Programs:
1.
Click Start, click Control Panel, and then click Add or Remove Programs.
2.
Click the program you want to remove, and then click Change/Remove.
If the system's instability has occurred immediately after a new device driver is installed, use the Device Driver Rollback feature instead of System Restore. To roll back to an earlier driver:
1.
Right-click My Computer, and then click Properties.
2.
On the Hardware tab, click Device Manager.
3.
In the Device Manager dialog box, double-click the hardware that uses the driver in question.
4.
In the device Properties dialog box, on the Driver tab, click Roll Back Driver.
See Charlie Russel's columns, Device Driver Rollback Beats BSOD and Finding Compatible Device Drivers for Windows XP, and Paul McFedries' column, Troubleshoot Device Driver Problems, for more information about device drivers.
Work through the Windows XP troubleshooters in the Help and Support Center. To open a troubleshooter:
1.
Click Start, and then click Help and Support.
2.
Under Pick a Help topic, click Fixing a Problem.
3.
Under Troubleshooting problems in the right pane, click List of troubleshooters, and then start a troubleshooter by clicking the name in the left column of the table.
If,after trying these options the computer is still unstable, opt forSystem Restore. You'll want to save this option for last because thechanges made to your computer are more comprehensive than if you simplyuninstall a program or rollback a device driver.
Use System RestoreAfteryou've decided to use System Restore to revert your system to aprevious state, start the System Restore Wizard and follow the prompts.To use the System Restore Wizard, make sure you're logged on as anadministrator, and then follow these steps:
