Has anyone had problems with crashes? I play Zombies 99.9% of the time and about 1 out of 5 times the game crashes. It's EXTREMELY annoying. I keep my laptop in a Coolermaster SF19 cooling pad, temperatures never go above 75-80. I'm playing at 1920x1200 & 2048x(whatever it is, I can't remember). My frame rates are always in the high 60's to 70's. I've used the latest Nvidia driver as well as the latest beta driver and it doesn't seem to matter. Anybody else out there having problems?
