I've been running Vista ultimate. Sometimes I can play for a few hours without it crashing, but lately it's been at most 10 minutes before it kicks me off.

I recently installed Bioshock onto my T400. The game runs well, but it randomly crashes and I get the message that the driver stopped responding and recovered, but the I have to reboot the game.

Is this a problem with my laptop, or is this a problem with the software?
