No crashes. But like I said, I never fired up any games or movies. All I did was check email. I've tried firing up and running just one application or game to see if it is software related, and what software is doing it, but I've come up with nothing. I've tested Steam itself, Counterstrike, DIRT3, BioshockII (all via Steam), Ventrillo, iTunes (as much as it kills my soul to use it), Trillian, and Chrome. None of those programs running by themselves have caused a crash.
