I upgraded the case a good while ago so a corsair slate(?) something like that, and there werent any issues then.

I'm going to try installing my old GTX 970 to see if that crashes as well.

mobo's on a box right now, 2nd brand new motherboard. Thermal paste is some MX-4. slightly unrelated but I've checked thermals and power levels and the crashes dont seem to correlate to any particular state.

I bought a 2nd new motherboard just to confirm the problem and its still happening. The pc is currently on a box right now and it still will randomly restart, most often under heavy load (doom crashes it most consistently) but sometimes it crashes just in chrome.

When I got the first new mobo I did a clean install of windows, purchased a new product key and everything.

Actually what I'm doing right now. I even went as far as buying a 2nd new mobo just to confirm thats the problem and it has the same issues.

So I decided to upgrade my old random OEM motherboard to a new AsRock z270 killer sli board for that overclocking. However now under the pc will randomly restart, no crash, no BSOD, nothing. Here are the current specs I5-6600k (no overclock) Gigabyte Windforce GTX 1070 Asrock fatality z270 (replaced as a troubleshooting step) 16 gigs of corsair vengeance ram 970 evo+ as a boot drive Unirex 480gig ssd as the steam library CX750M PSU (750watt, was replaced as troubleshooting step) Troublshooting steps already taken: Replaced PSU with a new one. (Same sku) Trying a competely different psu Reseating ram Reseating cpu Installing into a completely different mobo Using windows memory test software Updating bios on mobo Updating nvidia drivers Rolling back nvidia drivers At this point I have to think its the GPU but everything was working fine untill i upgraded the mobo so unless something went wrong during the rebuild I really dont know what else to try.
