This has happened many times now for my friend. I have posted on this board numerous times now for this very reason.
The issue is:
After a seemingly unjustified and fairly long period of time with the computer on - it would randomly turn off. Then you'd turn it back on and it would lift off, then turn off again after a number of seconds. Unplug the power cable for a bit then plug it back in and it works for a while longer - however the issue came back and it would do the same thing. There's nothing that he does to make it turn itself off. Literally nothing he is doing would cause any considerable power strain.
He has now replaced his power supply to no success. He noticed this happen for the first time a few months after switching out his PSU and GPU a few months back.
The component change was Arctic Power 450W -> Corsair CX500 and the graphics card a AMD HD Radeon 5570 to a 6850. The power supply was then changed again to an OCZ ZS Series 550w.
A few days before the issue reoccured, he said that he heard a strangely loud rattling coming from the computer, he turned it off and opened it up. Upon turning it on, the noise was gone. We dismissed this as the case door not being on right, but it might mean something to you guys.
Also his temperatures are always fine at the point of the computer turning off, as I said - it's nearly always idling or near idling when it does this.
After changing the power supply, the issue seemed to stay away for a while, but now it's back. Again. Seriously. What.
[b]His complete specs[/b]
ASUS AM3 motherboard (I'll get specifics if needed)
4GB DDR3 Value RAM (Single channel)
AMD HD Radeon 6850 1GB
500GB HDD, 5400RPM
A semi-generic mid-tower ATX case
OCZ ZS Series 550W
Any ideas, FP?

This can be done with HWmonitor. [url]http://www.cpuid.com/softwares/hwmonitor.html[/url]
Eww, ASUS. I'd blame that right there.
I had a similar issue of a motherboard randomly rebooting / turning off and it turned out to be a corrupt BIOS, but on the backup BIOS chip. If that motherboard has dual BIOSes, you might try and reflash the BIOS with the latest available for it.

It's not at current booting into Windows - but he had checked the temperatures just before it turned off and the highest one was 60C, and that was the GPU.
He was playing Minecraft at the time.

Excuse my lack of knowledge, but how would we go about doing that, and would it break the OS and require him to reinstall it?

Go to ASUS and find a bios download then google how to update a bios. It's somewhat long and it's best for you to just look for yourself.

Make sure that you look up how to flash the bios for your particular board.
