Question Lose Display and GPU Fans Ramp Up

[sfrench11189]

Been having this issue for a week, when while gaming I'll suddenly lose my display, will hear a windows error pop up (but of course can't see what it is), and my GPU fans will ramp up to max. I have a large list of things I've tried and have been unable to fix it. First go to of course was thermals, thinking it overheated, but that doesn't look to be the case. I'll try to make this as short as possible. In order (more or less)

• Used DDU unistaller to remove drivers and reinstall them. Also did the same to try old drivers.
• Removed and reseated the GPU
• Ran Heaven Benchmark 4.0, no crash/errors
• Ran Freestone Grooup GPU stability test, no crash/errors
• Ran 3DMark Timespy, no crash/errors
• Used the EVGA software to log voltages/temps around crashes, didn't notice any abnormal spikes/drops
• Updated BIOS
• Ran the windows memory check
• Ran the windows system file checker
• Ran Driver Verifier, resulting in a couple blue screens saying it found driver violations, causing it to go into self repair and roll back windows a bit
• Recreated the crash right after this, but upon restart this time I got a blue screen I couldn't repair or recover from
• Formatted drive and reinstalled Windows
• Reset CMOS
• Moved GPU down to a different PCIe slot
• Set TdrDelay to 8 in registry
• Changed power profile in Nvidia control panel to maximum performance
• Checked 12v rail in BIOS, was within tolerances
• Ran 3DMark Firestrike, no crash/errors. Used HWInfo64 to log data during this, will link below.

Since my last crash I updated all my MOBO drivers, but haven't played anything yet to see if that somehow fixed it.

Some other information that may or may not be useful. Prior to the Windows reinstall, I was only getting error dumps sometimes when it crashed that I could look at in WinDbgPreview and BlueScreenViewer. These crashes were pointing at something called watchdog.sys as the cause.

On the fresh install, I haven't gotten a dump file that's being picked up by WinDbgPreview or BlueScreenViewer yet. Using Event Viewer, I see an error the directly precedes the two crashes today called EnhancedStorage-EhStorTcgDrv. Now, this error shows up both times I've crashed today. But it's also shown up a couple times that hasn't resulted in a crash. So I don't know if it's related or not.

I'm stumped. I'm back and forth between thinking it's a GPU hardware issue, an issue with my PSU, or some kind of software/driver issue. Trying find someone else's system I can try my GPU in to narrow it down, but I don't have another one readily available. Worst comes to worse I can mail it to my brother. Or just by a cheap 1050 TI on amazon and test it with that. But hoping I can find the cause before having to go that far.

Anyone else have any ideas/ suggestions? I think my next step is going to be to create a log with HWInfo64 and try to recreate the crash, and see if anything of note shows up in that.

My system:

Asus Prime Z370-A Motherboard
EVGA GTX 1080 FTW Edition (not overclocked)
i5 8600k (also not over clocked)
8x2GB DDR4 Corsair Vengeance RAM
Corsair AX850 Gold PSU
Crucial MX something SSD that my OS is installed on
3 WD HDDs for games/storage

Small update, I was trying to reproduce the crash to get the log (which didn't look like it saved the last few minutes up until the crash, so I'll have to do it again). When I restarted Windows scanned and repaired my C drive, I don't think I did anything manually to initiate the scan. When I got back into Windows I saw I had a notification in the task bar saying "ACValhalla.exe has been blocked from accessing your graphics hardware"

Not sure if that's been there after every crash or not.
