Recently upgraded machine keeps restarting at random intervals.
I ran a Memtest, a Disk check, and Can run the GPU in games for about 2-3 minutes.
Temps have not gone above 35-40 degrees Celsius for any components in the case
All of the cables seem to be properly fitted. It also is not virus related as far as i can tell.

My system is as follows:

PSU: LEPA G800M Max Gold Semi-Modular
Motherboard: MSI 760GMA-P34 (FX)
GPU: Sapphire 4gb Tri-x R9 290x at the Factory Overclock
CPU: AMD FX-8320 at stock 3.5 Ghz
RAM: 2x 240pin 8G Corsair Vengeance 1600mhz (running at 1333)
CPU Heatsink: Zalman CNPS9500A
HDD: Western Digital 1.0TB WD10EZEX (Blue) (Boot drive)
HDD2: Western Digital 1.0TB 1003FZEX (Black)
OS: Windows 8.1

Thanks in advance for any help guys.

Edit: My HDD almost never runs below 86% and is often at 99-100% usage. Its been that way as long as I can remember.

thanks for the quick response, i figured that might be it. Will do, i was looking at the new CORSAIR RM1000i 1000W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Active PFC Power Supply. Would that do the trick, or can i reliably stick with an 800w PSU?

I disagree. Seen plenty of similar rigs with 700W bronzie PSU's running just fine. You are running mech HDD for OS? When PC randomly restarts, its usually bad sectors on the HDD, where the OS file have been written or faulty RAM. Memtest doesn't always reveal faulty RAM and bad sectors are a pain in the @ss to diagnose. Use Crystaldiskinfo to diagnose HDD's. Blue is good, yellow is bad...

itis a slightly different board, being the GMA as opposed to the GM. supposedly the fx 8320 and 8350 will work but will put a lot of stress on it. i have been running this machine with a gtx 760 and the 8320 with a 600w PSU for nearly 2 years until about 3 days ago when i upgraded to the 800w psu, corsair vengeance RAM, and the r9 290x

Edit: Its also listed as compatible on the manufacturers website. according to http://us.msi.com/support/mb/760GMA-P34-FX.html#support-cpu

ALSO, the fans do not stop spinning or anyhting like that. power doesnt seem to be interrupted and causing the reboot. PC seems to freeze for about 2-3 seconds before rebooting.

Can you try putting the GTX760 in and see if that runs fine? It is a possibility you got either a bad card or PSU, even could be BSOD from bad ram which would do restart if set so in BIOS. Change your BIOS setting to not to restart on failure.
If you have the old parts it is a process of elimination, swapping one at a time.

I am able to run benchmarks and stress the GPU, (sometimes for 10 minutes, sometimes for 30seconds) the problem persisted when I used the old 2x 4g ram chips. Going to try underclocking my 290 before I plug the 760 back in. Do I have to test the 760 with the drivers installed and under load? I don't see a bsod but I have been reading that it might still be a bsod even if I don't see it. This seems to be actually a somewhat common issue with these r9 200 series cards. I really don't want to RMA this card.

I found the solution. I set my BiOS to default and disabled quick boot. I disabled the GPU in device manager and it quit rebooting. After hours of trial and error installing the latest drivers, enabling the GPU, installing the 14.4 drivers, rinse, repeat. I found that the only drivers that have stopped the constant reboot were the 15.8 beta drivers which I was weary of.
