Need BSOD help; only BSOD's when playing BF:BC2

[MrMatt]

Ok, so my system setup is in my sig. I have Windows 7 Premium. If someone could tell me where the dmp files are stored after the system BSOD's I'd appreciate it. Also, can anyone read them? This is really pissing me off. I think it has to do with my gpu overheating, but I'm not sure. It only happens after I've been playing for a while, and at intermittent intervals.
