Hey everyone. I really dont post here unless im at a loss. My computer crashes and restarts during gameplay, at first only on high settings now even with lower settings, on multiple games (fortnite, apex legends, star wars battlefront 2 even). Happens once an hour, sometimes goes a few hours. This is with no overclock or boosts.

First what I have done so far:

I used amd cleaner and reinstalled GPU drivers, multiple times even rolling back at times. I have spent so much damn on AMD drivers, so its not this.

Updated BIOS

Undervolting - no difference

Underclock - no difference

Really done everything on Afterburner/wattman/bios i could do, all independent of each other; i know to only use one to OC or UC.

Always monitoring temps, never seen any temp above 85

fans work fine, my case is pretty "cool"

Cleaned case and all fans, no dust at all really.

Cyrstal Mark for disks check out

The card looks good, but I cleaned it with air, reseated and checked connections.

My GPU Temps rarely get above 85c at max so I don't think it's overheating.

My cpu is fine no heat issues.

Tried different outlets

No crashes on a unigine benchmark or 3 hours of prime95.

All these component bought in 2016.

It does crash instantly when i run anything past 720 on FurMark. I can usually play a few games, and then at the beginning of loading the game, or at the end of a match when i "quit match" it will crash restart.

I havent checked RAM, but i use alot of Adobe stuff, and i have never crashed.

I suspect PSU? I dont have one to borrow, may buy one at fry's and return if not the problem.

I have not tried to re apply thermal paste, seems a bit extreme but im at that point i guess, but like i said, i saw no temp past 85 sooo idk about this

Have not "changed" the seating position for my gpu on the PCI slots, or ram placements, but that seems unlikely cause. Though my GPU is heavy as hell.

Contacted EVGA for PSU and MSI for GPU regarding warranty, well see about that.

Anything else i can try guys?
