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.

Click the Start button and click Control Panel.
2
Under Pick a Category, click Performance and Maintenance.

In the System Properties window, click the Hardware tab.

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
(see page 90) or install a new driver.
