A driver is software that allows your computer to communicate with hardware or devices. Without drivers, the hardware you connect to your computer—for example, a video card or a printer—won't work properly.
In most cases, drivers come with Windows, or you can find them by using Windows Update and checking for updates. To do so, click the Start button, click All Programs, and then click Windows Update.
If Windows Update doesn't have the driver you need, check out the Windows 7 Compatibility Center, which has direct links to driver downloads and manufacturer support pages. For more information, see Update a driver for hardware that isn't working properly.
