Were you performing any CPU intensive tasks prior to the shutdowns?
Your case could be poorly ventilated, as evidenced by your temperatures going down when operating it barebacked; is it dusty?
We could glean more clues if you fill up the rest of your system specs by following this tutorial:- System Info - See Your System Specs
Okay, I followed the tutorial and filled in the specs. It didn't fill in what my PSU is, but it's a Corsair CX600. I don't know whether that's relevant or not.
The first shutdown occurred while I was asleep. The second one was after about 45 minutes of use. I had Steam, Firefox, AIM, Peggle (browser type videogame), and a couple other programs running.
My case sits in the bottom shelf of my desk. The side panel has little holes in it for airflow (though the fan for it broke when I bought the case), and the front and back have fans (one on each side).
I inspected it for dust, and it is very dusty. I will get a can of compressed air tomorrow.
I hope my system specs help glean something from what is going on.
