Well, today i've been struggling to find out what wrong with my PC... yesterday I unparked my cores for obvious reasons and it was all fine, booting up today and when gaming whether its CS:GO or BF4, the PC randomly shuts down and restarts... no BSOD or anything

I'm re-downloading the NVIDIA drivers now to re-install but when running furmark the computer is fine, no restarts, and only hitting up to 75, before i turned it off....

Kinda getting worried as this is alot of money and looking into it there is alot of posts regarding PSU and GPU failures

I have also recently installed windows 8.1 but ive been running fine for 4 days with better performance...

CPU and GPU temps are good, nothing above 75 on GPU and 60 on CPU

SPECS

AMD FX 8350 (OC'ed to 4.2) - No problems before but will try disabling it
Coolermaster V8 GTS
Gigabyte ga-970a-ud3p
MSI GTX 780 OC gaming edition
2 shitty harddrives
Corsair cx750m

UPDATE:
just installed drivers, said there was no compatible hardware in the PC???? GPU issue?

If it were a GPU failure you would typically get a BSOD. However you said that you didn't get one which leads me to believe that it is either a PSU failure like you mentioned, or you may just need to flash you bios with the latest update.

My pc was giving me issues like this a while back, and after a quick flash of my BIOS all of my crashing problems went away. I would suggest you try that first.

power issue, check supplemental power connection from the power supply directly to the GPU. if the connection is bad, the GPU will pull too much power thru the PCI bus and cause your motherboard not to have enough power to your CPU, when the voltage to the CPU drops below a certain point the CPU will reset. A good motherboard might refuse to turn back on, same with a good powersupply (a crappy power supply and motherboard might catch fire and burn out your PCI slot your graphics card is in, burns out your graphics card at the same time.

It's happened to me before, so possibly.
