GPU Shutting Down

Opster · October 8, 2018

Today in the morning when I turned my PC on everything seemed fine until about 20 minutes later my screen went black and it said there was no connection. So I clicked the restart button on my case and it booted up until the screen when it asks for my password, then it turned off again. At this point I looked at my PC and noticed that everything was still running and working except for my GPU. I'm not sure what the problem is as when I googled to see if others had similar issues some said it was the PSU. I built this PC about a year ago and everything was working fine until a couple of weeks ago when I started getting notifications on CAM that my GPU had exceeded 81°C. At first I thought it was that the case was to cramped and the GPU wasnt getting enough air so I bought a new case (Corsair Crystal series 460x) and transferred everything over. I also bought an NZXT Kraken x52 for my CPU. After I checked that everything was good to go I set up a custom fan curve for my GPU so that if it hits 70°C it will ramp up to 100% fan speed. Ok so this seemed to have worked as I had no issues for a week. Then after playing Dragon Quest 11 at the highest settings for about 3 hours I noticed that I had a CAM notification that my GPU had exceeded 84°C. So at this point I decided it was time to water cool my GPU. I decided to not play any games until the water cooling kit arrives. But as I said in the beginning, today my GPU just completely shuts off before I can even log on. I never overclocked my GPU either. My full Specs:
CPU: Ryzen 1700x
MB: Msi b350 tomahawk artic

RAM: Corsair LED 16g 2400mhz
GPU: MSI The Duke OC 1080ti
PSU: EVGA 650w 80 plus Gold
NZXT Hue+ (4 rgb fans)
NZXT Kraken x52 (using the Hue+ fans)

~~Did you oc your system? If yes, first thing I would do is disable the oc for cpu and gpu~~.

NM I should leard to read....

I have no experience with that msi card but the cooler looks beefy and should keep the gpu under 84c. Did you notice any performance hit from clock throttling?

~~If you didn't oc the gpu~~ it might be worth to remove the cooler and check the condition of the thermal paste. Maybe it has gone bad - could explain the temps.

Also do the generic stuff: Undo any latest software changes (driver, os update etc). Reinstall all the drivers and check for proper cable connection.
