Reinstalling Drivers and Utilities

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.
Windows XP:

Roll Back Driver.

2 Click Properties→ 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.

Roll Back Driver.
If Device Driver Rollback does not resolve the problem, then use System Restore to return your
computer to the operating state that existed before you installed the new driver (see "Restoring
Your Operating System" on page 106).
Using the Drivers and Utilities Media
If using Device Driver Rollback or System Restore (see "Restoring Your Operating System" on

media.
