Thilly:
Yes the GPU (which I guess is the videocard) is usually about 66-70ish when Idle, however it is about 75+ when playing a game, usually.
But for some reason I do not think its because of the graphic card, and its a GT 120 btw, not GTX 120. But the GT 120 max temp should be about 105 C.
I've read posts from other user about this same Computer model and it seems it could just be the way the computer was built. It didn't came with any case fans, but it still shuts down even when I've only added 1 case fan so far. However, I think the problem could be solved (or maybe just temporary) if I place a big fan right next to it, I hope that works at least, but I've yet gotten myself a new fan to try it >_>
Well anymore advice is appreciated, thanks.
