Reinstalling Drivers and Utilities NOTICE: The Dell Support website at support.dell.com and your Drivers and Utilities media provide approved drivers for Dell computers. If you install drivers obtained from other sources, your computer might not work correctly. Using Windows Device Driver Rollback If a problem occurs on your computer after you install or update a driver, use Windows Device Driver Rollback to replace the driver with the previously installed version. 1 Click Start , and then right-click Computer. 2 Click Properties, and then click Device Manager. NOTE: The User Account Control window may appear. If you are an administrator on the computer, click Continue; otherwise, contact your administrator to enter the Device Manager. 3 Right-click the device for which the new driver was installed and click Properties. 4 Click the Drivers tab, and then click Roll Back Driver. If Device Driver Rollback does not resolve the problem, use System Restore (see "Restoring Your Operating System" on page 124) to return your computer to the operating state that existed before you installed the new driver. Using the Drivers and Utilities Media If using Device Driver Rollback or System Restore (see "Restoring Your Operating System" on page 124) does not resolve the problem, reinstall the driver from your Drivers and Utilities media. 1 With the Windows desktop displayed, insert your Drivers and Utilities media. If this is your first time to use your Drivers and Utilities media, continue to step 2. If not, proceed to step 5. 2 When the Drivers and Utilities installation program starts, follow the prompts on the screen. NOTE: In most cases, the Drivers and Utilities program starts running automatically. If it does not, start Windows Explorer, click your media drive directory to display the media contents, and then double-click the autorcd.exe file. 3 When the InstallShield Wizard Complete window appears, remove the Drivers and Utilities disc and click Finish to restart the computer. 122 Troubleshooting
