Identifying Drivers, 117 | Dell RW491 specification

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 Start , and then right-click Computer.

2Click 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 continue.

Scroll down the list of devices and check for an exclamation point (a circle with a [!]) next to the device name. 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 117).

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 Start , and then right-click Computer.

2Click 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.

3Right-click the device for which the new driver was installed and click Properties.

4Click the Drivers tab, and then click Roll Back Driver.

If Device Driver Rollback does not resolve the problem, use System Restore (see "Restoring Your Microsoft® Windows Vista® Operating System" on page 120) to return your computer to the operating state that existed before you installed the new driver.
