I've had this comp for about two years now I think. The processor in question is a Phenom 9950 BE, It's been running hot since I got it, but latley has been causing blue screen shutdowns, and has been over 100c when playing Dragon Age. ( according to AMD Overdrive Status Monitor, Speedfan, and Coretemp alike.) I've opened it up, applied new AS5 ( yes, correctly, right from the website ). And made sure I've seated the heatsink correctly ( is the stock one that came in the box. I've got 3 case fans in total, would be 4 but the 120 in the side door is broken. Would buying a aftermarket heatsink help the problem? Or am I missing something? Oh, and when I opened it up, I vacuumed out all the dust humanly possible, and airdusted the rest out.
