Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.
A driver acts as a translator between the device and any programs that use the device. Each device has a set of specialized commands that only driver for
that device recognizes.
Required drivers are already installed on your computer—no further installation or configuration is needed.
Many drivers, such as the keyboard driver, come with your Microsoft ® Windows ® operating system. You may need to install drivers if you:
l Upgrade your operating system.
l Reinstall your operating system.
l Connect or install a new device.
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, then click Control Panel.
2. Under Pick a Category, click Performance and Maintenance.
3. Click System.
4. In the System Properties window, click the Hardware tab.
5. Click Device Manager.
6. 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 appears next to the device name, you may need to reinstall the driver or install a new driver (see Drivers ).
Reinstalling Drivers
Using Windows XP Device Driver Rollback
If a problem occurs on your computer after you install or update a driver, use Windows XP Device Driver Rollback to replace the driver with the previously
installed version.
1. Click Start, then click Control Panel.
2. Under Pick a Category, click Performance and Maintenance.
3. Click System.
4. In the System Properties window, click the Hardware tab.
5. Click Device Manager.
6. Right-click the device for which the new driver was installed, then click Properties.
