My computer just randomly keeps turning itself off, normally its when I play games but occasionally not. At first I thought It was overheating so I installed some monitoring software and It was no overheating. I have checked to see that everything is plugged in properly and secure and everything is. I'm stuck and I have ran out of ideas on what to do. Please help I think it may be something to do with the CPU or PSU any ideas will be greatly appreciated. Also sometimes this incident wont happen for weeks but when it does happen my computer ends in a continous reboot.
I would bet on the PSU. Next time it shuts down if you can open the case and put your hand near the PSU (Don't touch!) you may be able to feel the heat coming off on it. I had a problem like this a while back.
