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.
Windows XP:
1 Click Start→ Control Panel.
2 Under Pick a Category, click Performance and Maintenance, and click
System.
3 In the System Properties window, click the Hardware tab, and click Device
Manager.
Windows Vista:
1 Click the Windows Vista Start button™ , 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 continue.
Scroll 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 52).
