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.

Please only post if you know what your talking about, I dont want to sound mean or anything I just don't want my pc screwing up.

Alright thanks, I posted on Tom's hardware and the response I got from them was that It's probably the PSU. I just want some more opinions.

I can see it being anything from the CPU, PSU, and the RAM.

Try and do a "memtest" to see if it is the RAM. If it is then simply buy new sticks or check if the ports are damaged on the MB.

Check/replace the motherboards onboard battery, similar to a cars battery that battery is used to start and maintain the motherboard until the PSU is up and running. If that is faulty then you have an issue.

The PSU you have seems a tad cheap. Not to say cheap things aren't good but if this happens during gaming, than the heavy load it is taking from other components may be sucking up more power than it can push to that certain piece of hardware making it restart.

Just a few things I have listed above may be the issue, I also ran into this problem and fixed it by getting a trusted Corsair 750w PSU. If you need information on how to troubleshoot feel free to PM me.

Ok I've kind of concluded that It's definitely the PSU, When I look in the logs it says kernel power and Tom's hardware have said PSU aswell. So my next question is If I'm replacing the PSU what kind of power output do I need?

Honestly you can probably just get another 600w, but this time something more dependable and better quality.

Here are a few:

it is prob the PSU, you said when you play games, your GPU/CPU is taking more than what the PSU can out put that might be why, very very bad brand go with something trusted like Corsair, Antec, XFX, Rosewell.

There is a simple test you can do to see if it is the PSU/CPU or GPU, Download Prime95 and also download MSI Combuster or Furmark, run both of them and see if your PC shutsdown.

Note:
The programs listed above put unreal stress on your hardware.
