My specs are:

OS: Windows 10 64 bit
Storage: 3x Adata sx900 128GB SSD in RAID (Two years old)
1x Seagate 750GB HDD (5 years old)
PSU: LEPA 850 W (Two years old)
GPU: 1x Radeon R9 290 w/ NZXT Kraken watercooler. (Not Overclocked) (2 years old)
Mobo: z77x Gigabyte UD3H Rev 1.0(BIOS f20E)
Processor: Intel Core i5-3570k (not overclocked)
RAM: Kingston HyperX 4gb x2
All my problems started when I upgraded my case and my operating system and tried to add another R9 to run in crossfire. My computer now shuts down randomly while playing games like Fallout 4 and Mass Effect 3. Even old games like C&C 3 Tiberium Wars cause a reboot. I have monitored my GPU and CPU temperatures and they are both well below 40 as I play and when the computer shuts down. There is no stuttering or reduction in FPS in the seconds leading up to reboot. It's a very abrupt reboot.

When putting this PC together and installing Windows 10 I was having driver issues all the time, The R9's worked just fine, until one day Crimson drivers just said no AMD GPU is installed. Swapped the cards around and found out one card is dead. So that got removed. Everything worked fine for a couple days after that.

Then I started getting BSOD's saying "Thread stuck in device driver". At this time I started monitoring temperatures of the GPU with GPU-Z. The VRM temperatures on the GPU were getting up to 92C! I installed VRM Heatsinks that fit under the watercooler, reapplied thermal paste and fired it up, computer worked fine for a couple days until... BAM random restarts, but back with a passion. Fallout 4 makes computer restart in less than 10 seconds. C&C 3 makes computer restart in about 30 minutes. Bioshock infinite takes 10 minutes etc etc.

tl;dr: Computer restarts randomly while playing games.

How do I rid this demon?

Things I have already tried:
Testing my RAM.
Monitoring my temperatures.
Making sure my drivers are all up to date.
Reapplying thermal paste to my CPU and GPU.
Cleaning case and components with compressed air.
Reformat and reinstalling Windows 10 (Four times)
I unplugged and replugged every single cable on the motherboard until I was sure there was a good connection.
I looked and looked for blown capacitors, bent pins, any kind of damage on both cards and the motherboard. Everything is a-okay.
