The past week or so my game keeps freezing after 5-10 minutes of playing. Once it freezing I can't turn off the game even using the task manager. It's happened about 6 or 7 times now.

So far I've tried updating my drivers, reinstalling the game and cleaning the dust out of my comp.

I'm using a Sager NP7280-S1
Windowd 7 64
Intel Core i7 950 3.07GHz
12GB ram
GeForce GTX 485M
have to find out my ISP info.
