Crysis crashing blue screen of death

Hello everyone,

I have a 8800gt oc 515mb card, and i didnt have any problems when i first started playing crysis. Now though when i play for awhile my comp will give me the bluse screen and restart. I think that it is my graphics cardm but not sure. Also when starting my computer, the desktop will boot up then the screen will go black then come back on again. my friend told me that its my card.

I have loaded the newest card updates, and it still does it. I also have an aftermarket cooling heatsink with a fan on it. HELP!!!

The blue screen flashes for like a second then my computer restarts. From what i can get from the two times it has done it i saw stuff reguarding nvidia and video. i apologize for what little detail i have. The memory is fine though, i do know that. I did a test a couple of days ago.
