Many drivers, such as the keyboard driver, come with your Microsoft Windows operating system. You may need to install drivers if you:

•Upgrade your operating system.

•Reinstall your operating system.

•Connect or install a new device.

Identifying Drivers

If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.

1Click the Windows Vista Start button™ , and right-click Computer.

2Click 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 continue.

3Scroll down the list to see if any device has an exclamation point (a yellow circle with a [!]) on the device icon.

If an exclamation point is next to the device name, you may need to reinstall the driver or install a new driver (see "Reinstalling Drivers and Utilities" on page 91).

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.

1Click the Windows Vista Start button™ , and right-click Computer.

2Click 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.
