Question PC black screened under load until GPU stress test

[Notmenosir]

On January 7, one of the programs I frequently use started crashing and giving messages my GPU drivers were out of date. After a few days of troubleshooting, I instead started getting black screens with no sound if I ran any program that needs more than a web browser needs. Second Life viewers, any of the Final Fantasy 7 remake games, for example.

Eventually, I took it to Best Buy to get its Geek Squad to run diagnostics on it. A mysterious stranger named Not Me had spilled something that caused liquid damage to at least the PSU. I replaced it, but still kept getting black screens until the Geek Squad ran a GPU stress test and left the PC running overnight. I took it home, plugged it into a different surge protector that's plugged into a different wall socket than the ones I'd been using before. I'm still using the same "monitor," actually a Hisense television.

So far, it's been two or three hours and there's been no black screen. I'm not totally convinced I'm out of the woods yet, but am slowly becoming cautiously optimistic. My question is, why would a GPU stress test, leaving the PC running overnight, and/or using a different surge protector and/or wall socket in the same room stop the black screen with no sound issue? I could just be glad things seem to be working again, but I'm really curious.

Not Me is no longer welcome in my house.



My hardware is:

Processor 13th Gen Intel(R) Core(TM) i9-13900K, 3000 Mhz, 24 Core(s), 32 Logical Processor(s)

Motherboard ROG Maximus z790 Hero

GPU NVIIDA 4090 ( specifically, TUF-RTX 4090 )

PSU Corsair HXi Series 1500w Platinum

Memory 64 GB Corsair Vengeance

Welcome to the forums, newcomer!

We'll need to know what that liquid that was spilled by Not Me, was. On a side note, you might want to use DDU to remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, then reinstall with the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

You might want to revert to the original wall out and surge protector and see if the issue persists. If it does then your wall outlet is compromised, like a grounding issue.
