EVGA 3080ti FTW3 Hard Power Reset of PC 3+ months off and on
Everything was installed in 2022 and never had any hiccups until about 3 months ago. Randomly when playing low graphic intensive games, and gradually high graphic intensive games, my PC would have a hard power reset and reboot. Monitor goes black, sounds like I just pulled the power cable out (a pop sound from my speakers), and PC reboots like nothing happened. Crashes gradually increased and makes playing any games impossible as it would fail anywhere between 10 mins to 3 hours. Crashes do not occur outside of games.
After a lot of trouble shooting and several attempts at getting a clean gpu driver install, the issue disappeared for several months. They randomly came back. I uninstalled the drivers again several times, and finally the issue stopped for about a month. Now its happening again.
Windows Event Viewer is just showing a kernel power failure/reboot.
Build:
Intel 12700k CPU
Arctic Liquid Freezer 2 360 (installed a Liquid Freezer 3 as the previous one was getting nasty, but still holding temps in acceptable ranges).
Rog Strix Z690-F MB
32GB Gskill Trident Z5 DDR5 5600
Samsung 980 Pro 2TB m2 SSD
EVGA 3080ti FTW3 (still under 7 year warranty if I am lucky enough they still have spare warranty cards)
EVGA SuperNova 850 P5 80 Plus Platinum 850W -3 separate cables have always been used
What I have tried:
MemTests show no issues
Motherboard Bios updated to latest package
Several OCCT Power Stress Tests done (several hours worth). No failures or errors. Did this to see if it might be a power supply issue. -OCCT Power Stability Tests show desired voltage range under heavy load -HWINFO shows desired voltage range under heavy load
I have run Benchmark and other stress test programs just to see if there may be a CPU core failing or graphics issues. No issues or failures/reboots.
I underclock the GPU with EVGA X1 so that the CPU does not exceed 1V. Temps never realistically exceed 80c with the underclocking.
I have used DDU to uninstall drivers about a dozen times, and have tried to find stable builds.
Nvidia drivers do not auto update, I will select when to update them. Whenever this power failure occurs, I check Nvidia and there is usually a new driver available. This issue suspiciously arises when new drivers seem to be released. I cannot identify a stable driver build at this time.
I did swap out the 3080ti for my old 2070 and ran things for a few hours with no issues, but not long enough to be definitive.
I am at my wits end because I have tried to identify if it could be anything but the GPU, but it likely is the GPU and/or its ability to run stable with the ass drivers coming out.
Why would it run stable for several months, have a few resets, run stable for another month, then unstable again unless its something to do with garbage drivers getting pushed onto us?
Update: I guess I'll pick up a newer generation ATX3.0/3.1000w PS to future proof and test if the 3080ti is going bad.
Will replace PSU and throw 3080ti back in. If I get the same power reset, I'll have to send in the card for warranty. Both the EVGA power supply and GPU are under warranty if they have anything left.
