I have an Abit Siluro Geforce 2 MX400, I downloaded the WinXP drivers from Abit and from Nvidia. When I try to install them windows complains that they have not been digitally signed. At first I ignored this and went ahead and installed the nvidia drivers. The problem is even before I had the XP drivers installed, the computer just plain refuses to play any games, crashing the whole computer within a couple of minutes of loading them up. Same applies for both drivers??? Does anyone have any suggestions??
