Updating drivers on vista
For assistance with the installation of a graphics driver, contact the manufacturer of the computer or the manufacturer of the computer's video adapter.To identify the manufacturer and model of the computer's video adapter or chipset, use the Direct X Diagnostic Tool included with Windows 8, Windows 7, and Vista.
Updating the graphics driver can resolve display issues in Adobe applications.
An updated driver might enable new features for the hardware, something I see on a regular basis with popular video cards and sound cards.
Tip: Updating drivers yourself is not difficult, but there are programs that will more or less do it for you.
Hardware manufacturers update the drivers (the little programs that enable Windows Vista to control the hardware) on a regular basis to deal with updates in Windows Vista itself and to improve their performance.
If you don’t keep your drivers up-to-date, you could run into problems that make your hardware malfunction.
