Crashing. Games like Alice and Jedi Knight II crash after 5 mins. help!!

I’m not sure if it is the openGL. But it only seems to happen with 3d games. or in these games cases ones running the Quake 3 Engine.

I have a Xpert 2000 32Mb AGP card. I’ve tryed up dating my drive. But no luck.

I’m running XP. Which probably doesn’t help.

Any ideas
