I have swapped GPUs, PSU, RAM, tried the other pcie slot, tried the other ram slot used ddu to uninstall all drivers multiple times and it still restarts.

What are your temps and did you change anything before this happened?

Those are my temps under stress. It recently started doing this after getting a new GPU. But now it still does it even after i swap back to my old one.

Odd, does it restart randomly or when you're doing a certain workload? You temps are fine. Power isn't a issue either, I have got a i7 3820 @ 4.625Ghz and a 390x with a 625watt psu and its just fine. Its either a faulty part or the motherboard could be giving some issues. Also, try setting the bios to default.

Didnt mean to select as solution. It seems to only restart when under load from playing games.

Alright, will it restart if its just sitting at idle? Do this (one at a time) (if one causes a restart then move on to the next, if they all cause restarts its your psu) 1st use either memtest86 or if you don't have a spare usb flash drive then just hit the windows key and type Windows Memory Diagnostic tool and run it. 2nd run a prime 95 test http://www.mersenne.org/download/ pick just stress testing then run a torture test then pick the one with max power consumption. last run furmark this will test your gpu http://www.geeks3d.com/dl/showd/522 pick 1440p preset. if they all fail see if you can at least do this one http://www.userbenchmark.com/ it will tell you how your components are comparing to alot of other samples.
