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:
1 Click Start→ My Computer→ Properties→ Hardware→ Device 
Manager.
2 Right-click the device for which the new driver was installed and click 
Properties.
3 Click the Drivers tab→ Roll Back Driver.
Windows Vista:
1 Click Start 
, and right-click Computer.
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.
3 Right-click the device for which the new driver was installed and click 
Properties.
4 Click the Drivers tab→ Roll Back Driver.
If Device Driver Rollback does not resolve the problem, then use System 
Restore ("Restoring Your Operating System" on page 98) to return your 
computer to the operating state that existed before you installed the 
new driver.
