The Witcher 2 Causes Entire System Freeze. GPU? CPU? Ram? PSU?

[Koalaman]

As the title states, when playing the witcher 2 (even in windowed mode) the game will freeze up my entire system. I don't think it's my CPU because it passed a 9 hour Small FFT Prime95 run, and I've got a Thermaltake T2-800W PSU. The only thing I can think of is the GPU. I haven't even had it for a month, and just before freezing the game will artifact. I'm going to re-apply TIM and see if it's a heat issue. I will report back.

I just replaced the TIM and my system still froze. I'm looking into getting an RMA.

I've come to the conclusion that it's just the game. I will be running Gpu Test and unigine to stress test my GPu because I don't want to go through the Rma process (especially since they send a refurbished card).
