So. I installed my last 2 ram 8GB (they're with the kit (4x4GB), i played CSGO for about 2 hours approx. Then my computer decides to shut offc completely. There's no warning, message, NOTHING indicating my computer is overheating, interrupted by anything, no logfile, nothing. I then tried to remove the last 2 ram i installed, no difference. I then tried to remove my graphics card (760 GTX OC), nothing. It's even running right now with my CPU as the display port.

Here's when the problem occurs:
1. When i run any game on my pc, it's shuts down instantly after 5 min of gameplay.
2. I tried to benchmark with heaven 4.0, shuts off at random times (meaning it's not at the same spot everytime, sometimes before, sometimes later)
3. At times it wouldn't even boot up, because it crashes / shuts down before it even reaches login screen to windows 10.
4. Even with or without the GPU installed, it crashes / shuts off

What have i done so far?
1. Made sure, my CPU cooler has complete contact with the CPU, no difference.
2. Removed my GPU, tested in CSGO (playing a normal DM), shuts off.
3. Installed my GPU back in, still shuts off.
4. Let my computer be for atleast 6 hours, tried to turn it on again. no difference.

When did it exactly start?
As i loosened my CPU cooler, so that it didn't bend the PCB's, so that all of my DIMM slots would work. I then played CSGO for 2 hours approx with all of my ram running, it then shuts off completely. I've had this issue ever since.
