@mariush:
I thoroughly dusted/cleaned out my rig about 2 months ago, and have filters on all of the intake fans. I've also tried 3 different sets of drivers, two WHQL and one beta, and found one that crashes less than the others. And... as for memtest, I ran it when this was first happening a couple of months ago and after 8+hours, had no errors reported.
Thanks guys for the input so far, I'm still tinkering with some stuff. I'm going to stress test with Kombustor and see if I can't replicate the crash outside of BF3
