Good point about temp! I actually did take it apart looking for the motherboard battery to clear out the bios and removed the memory to clear that as well. I took a look at the processor, the heat sink was clamped down pretty well onto the processor. But there was no compound inbetween. Now the only thing thats making me think it isnt the temp is that the comp will sometimes run for over an hour either idle or 1/2-3/4 load with out any problems. And then sometimes we would just turn it on from a cold 8 hour rest, and the problem would come up. I've taken pc's apart before but let me tell you, this thing was a pain to take apart, I'll give the thermal stuff a shot but I'm not looking forward to ripping this thing apart again. Thank you for the suggestion!
