Graphics Card help

How do you tell what graphics card you have in a computer so that you can download the correct driver, when Windows Update cant find the right one?

Do you at least know the brand? Nvidia has a large download that has the drivers for most of their recent graphics cards going all the way back to like the GeForce 2's or something.

Also, check the device manager, right click My Computer, select Properties, then go to the Hardware tab, and then look for the graphics (or display) card, that might give you more information. I'd help you more right now but I'm on a mac so I can't go through the steps to tell you what to look for, but when I check back (it might be later in the weekend b/c I'm going out of town) if nobody has helped you more I'll see what I can do
