source of your problem and, if necessary, update the driver.

Click Start , and then right-click Computer .

Click 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).
