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.
1 Click Start → Control Panel→ System.
2 In the System Properties window, click the
Hardware tab, and click Device Manager.
Scroll down the list of devices and check 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 39).
