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 like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only
its driver recognizes.
Dell ships your computer to you with required drivers already installed—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 Vista
If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.

2. Click Properties® Device Manager.
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).
