Okay I installed GPUz (sorry for the overly delayed response). It seems I idle at 46-49 degrees and when I open a game (UT2k4) it shoots up to 57. This is without the heating on in the house.
The game stops, tv flickers to no signal, then the game is playable again.
If I go into windows this is what I get:
Display driver stopped responding and has recovered.
Display driver amdkmdap stopped responding and has seuccessfully recovered.
