What if I have no idea what motherboard it is? Is it possible to find out just by looking at the insides of the computer, or from the boot/setup menu?
Edit: I think it is a Dell XPS 600, as the sales tag says XPS 600.
What I copied down from the Setup Menu was: Dell DxG051 Bios ver: A11
I'm looking at the Dell website, and I have no idea which driver I would want.
