So I've been having quite a few problems recently with restart in the middle of a game. I'm playing far cry 3 and about an hour in the computer just restarts without warning.

I did memtest and got nothing so after that I tried Prime95. Firstly I did the blend test and as soon as I pressed the test button the computer restarted itself. Then I did the small FFTs and the same thing happened.

Does this mean the CPU is messed up?

I'm using an AMD FX-8320 with the stock fan. Haven't overclocked or anything yet.

Lemonade!!...am sorry man. I feel like an idiot. I saw your HWmonitor screen shot again and all of your your voltages are falling short. Not even the +3.3 and +5 voltages are running at the required values. they should only deviate about +/- 5%.
Your psu is the culprit and is probably undervolting the system by not holding the correct Vrail voltage.

As a final nail in the coffin test, you can try running your system with another psu and see if the issue persists. It likely won't. Great guess Egilbe and Augman. nice work :)

I tried memtest and got no errors so I don't think it's RAM. And I don't know if I got any errors in prime95. It literally just turns the whole PC off as soon as I press test.

AMD FX-8320
MSI GeForce GTX 760 2GB
8GB DDR3 RAM (Dunno which make or anything. It's just one stick though)
Corsair CXM 600W

That's what makes me think it may be the PSU. Who makes the PSU? rated Wattage? Try moving the stick of Ram to a different slot.

Odd case, but i will have to agree with egilbe, it really sounds like a PSU being overloaded when you press test and usages go to 100%. You've more than likely ruled out the RAM, and i dont think its possible for the cpu to be the culprit at stock clocks, only maybe if your mobo doesn't support the high wattage cpu... Then again you mention its a corsair 600watt, which is odd because corsair is top tier power supplies, and i think that psu should be able to handle that rig fine.

Those temps are do-able. Not great, the gpu temp could stand to be a little lower, but i cant see those temps shutting off your pc completely... I use to run with temps like that for years.

Ah i didn't see the link until now, to be honest im not familiar with what hardware monitor calls the gpu as far as temps go. I use the windows 7 desktop gadget called cpu-meter and gpu meter, and as i have multiple monitors, i let them run off to the side so i may glance at them anytime

So it just happened again and when checking action centre here's the message I got.

The computer has rebooted from a bugcheck. The bugcheck was: 0x00000124 (0x0000000000000000, 0xfffffa80082428f8, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\Minidump\030214-19780-01.dmp.

Okay lemonade, your error code is 0x124...that is a generic code indicating that windows shut down due to an uncorrectable hardware issue. I imported your dump files into my system's minidump folder and used bluescreenview to find out the error code.

Now, the first suggestion to address this error code is that it is rarely driver related and mostly caused by a hardware issue. You may have to reseat every component(especially the rams) except the cpu and check again if the issue persists.
