Getting a lot of random restarts with my new build

Problem: Random restarts, no BSOD or freeze, system will immediatey turn off then turn back on again. Happens multiple times at varying intervals (2 Hours, sometimes only 2 minutes), mainly while benchmarking and gaming. I posted another thread about this, but marked as solved because I thought I had fixed it.

What I tried: Ran memtest twice, showed monitored temperature (65-68CPU, 60 GPU), switched out power supply (Corsair CX 600 to TX 750), updated GPU drivers, ran drive sweeper, changed misc power settings in BIOS, checked hard drive for errors, and updated BIOS. What else can I do?

My system:
- Gigabyte GA-B75M-D3H Micro ATX LGA1155
- Intel Core i5 3470
- Corsair XMS3 DDR3 133Mhz 16GB (4X4GB)
- Sapphire Radeon HD 7870 XT
- Corsair TX 750 V2
- NZXT phantom 410
- Seagate Barracuda, 500gb, 7200rpm
- Lite-on CD drive

I noticed RAM was pretty hot too, is it possible for RAM to overheat causing a shutdown? It got pretty hot during testing and resting my fingers on it was close to burning them if I left them on overtime.

The power / reset headers are snug and seem fine, when I opened my computer to check, I noticed something I had never seen. One pin on the USB 3.0 header is bent, I removed the USB cable from the motherboard header. Could that have been the culprit? Currently running more stress tests.
