How to Fix My Display Driver for Vista

Display drivers allow your video card to interface with the Windows Vista operating system, games and other applications. Bad display card drivers may cause strange graphics problems such as visible artifacts, discolorations, out of place lines and other problems. Prior to fixing your display driver, you must determine whether the driver has been recently updated or if your already-installed driver has become problematic. If you have recently upgraded to Windows Vista from an earlier version of Windows, you must install a Vista-compatible driver.
