Everytime I play games, such as Bionic commando, Anno 1404, COD 5, my computer shuts down after 5-10 minutes of gameplay. It's like someone pulls the plug. After that, I can turn on the computer without facing any issues.
At first I thought my cpu was the problem, cause apparently my q9300 ran (idle) at 60(according to speedfan) degrees celcius. So I cleaned my case and my cpu cooler(scythe mugen infinity), removed the dust and the temps dropped with almost 10 degrees. However, the shutdowns still occur.
I think my cpu cooler isn't working properly or might it just be my psu that is failing constantly? I really need to get this pc up and running again, for there is much gaming to be done.
Any ideas?
Many thanks in advance.
*update*: I read that increasing my cpu temp limit in the bios might help. It's currently on 45. Is this a good idea and what would be a suitable temperature to put the limit to?
