My Computer Keeps Shutting Down

I recently built my own computer, a few months ago. Over the past week it's started to shut itself down after its been in use for 5 minutes. I've cleaned out the inside and it doesn't seem to be heating up too much - I've also ran various registry cleaners and AVG 2012 which turned up no serious errors (in which any minor errors were resolved).

I don't know what could be the problem. I've changed the PSU so it's not that. This is my last resort before buying a new computer but I'm still anxious about that, simply because I spent quite a lot on this computer.

The componants are:

500W PSU
AMD FX Processor, 3.6 GHz
AsRock 9600-GS3 FX Motherboard
4GB Random Access Memory

It was fine for the first few weeks and then boom, it started going wrong.

ANY help would be appreciated. Thanks in advance.

It could be anything. From my experience it sounds like bad capacitors. Either in your PSU or MB. Check your caps on your motherboard, but good motherboards today have solid caps, so a blown cap is pretty rare.

The PSU you put in, is it new? Is it a brand name?

OK here are few things to help trouble shoot it

1) Update bios(if possible)
2) Clear Cmos, do this if you cant start or have messed with the bios(don’t forget to unplug the computer from the wall and let it sit for few minutes, if you don’t have a jumper than remove the battery make sure the computer is unplugged and let it for about10 minutes before putting the battery back in)
3) Check your psu
4) Make sure your computer is hooked up correctly
5) Run memtest(if possible)
6) Run Burnintest (if possible)
7) If all else fails then try a gpu, Ram, or psu from another computer
Hope this helped! :D 

One last thing how are your temps under load?
