PC randomley shuts off and keeps trying to start up

[ZemphY]

Hi,

So I recently upgraded to the M5A99X motherboard and upgraded my CPU to the AMD FX-8350.

I've had my computer on properly today updating and installing programs (had to perform a clean install of Windows 7). I had my PC running for about 4 hours straight and then it shut off without warning (like someone pulled the plug out) and then it automatically started up, after about 10-15 seconds it shut off again and then tried to start up... It keeps repeating this till I pulled the plug out.

I haven't turned it on since it happened, do you think it was because my CPU overheated? I'm using the stock heat sink and it had pre installed thermal paste on the bottom of the heat sink.

So yeah, any suggestions?

Thanks,
Z

I doubt it's cpu temps. I think it's your motherboard.

You sure?
What specifically on the motherboard would you say is causing the problem?

I don't know specifically which part of the motherboard might be failing but it sounds like an issue with the motherboard to me.

It sounds like the PSU to me.
