Reinstalling Drivers

NOTICE: The Dell Support website provides approved drivers for Dell™ computers. If you install drivers obtained from other sources, your computer might not work correctly.

Using Windows XP Device Driver Rollback

If a problem occurs on your computer after you install or update a driver, use Windows XP Device Driver Rollback to replace the driver with the previously installed version.

To use Device Driver Rollback:

1Click the Start button and click Control Panel.

2In the Control Panel window, under Pick a Category, click Performance and Maintenance.

3In the Performance and Maintenance window, click System.

5Click Device Manager.

6In the Device Manager window, right-click the device for which the new driver was installed and click Properties.

7Click the Drivers tab.

8Click Roll Back Driver.

If Device Driver Rollback does not resolve the problem, then use System Restore (see page 49) to return your computer to the operating state that existed before you installed the new driver.
