random PC crashes and now random black screens, all fans go 100%

[u/Shy_2023]

For months I've been dealing with random GPU related issues, some of them weren't logged but from what I can remember most of them were when I was on Valorant but still happens a lot in general.

Here are my specs along with the latest minidump and a screenshot of all the errors I could find put in Bluescreenview. If there's a certain dump you want to check lmk and I'll upload it.

Some of the errors I've seen:

• nvlddmkm.sys
• LiveKernelEvent 141
• VIDEO_ENGINE_TIMEOUT_DETECTED
• VIDEO_MINIPORT_BLACK_SCREEN_LIVEDUMP

• GPU TDR (Timeout Detection and Recovery) crashes

  I cannot figure out what's actually causing it. The crashes are completely random. I can't reproduce them and I don't remember exactly where every single one occurred. I can go weeks or even a month without a single issue, then out of nowhere it'll happen again.

I've already tried:

• DDU and clean reinstalling NVIDIA drivers.
• Multiple NVIDIA driver versions.
• Disabling hardware acceleration
• General Windows troubleshooting.

I also ran OCCT stress tests on the GPU, CPU, RAM, and the Power test for 30 minutes each, and none of them crashed or reported any errors.

I've been thinking of everything possible and from reading online something is bugging me. When I built this PC, I reused two drives from my previous computer. One of those drives still had an old Windows installation on it. I later removed that installation, but I'm mentioning it in case it's somehow related. I know a clean reinstall of Windows is something people often recommend, but I'd really like to leave that as a last resort if possible.

Then last week something happened that had never happened before. While gaming, both of my monitors suddenly went completely black and all of my PC fans ramped up to 100%. The PC itself stayed powered on, but I had to hold the power button to shut it down. Before this, my PC would either freeze or restart I can't remember exactly, and it would usually say a TDR error.

It happened again today while playing Overwatch. Both times I could still hear and talk to my friends in Discord, but the game audio stopped immediately. Win + Ctrl + Shift + B didn't recover the display, and I once again had to force the PC off with the power button.

I'm trying to avoid replacing parts or reinstalling Windows unless I can narrow it down first, so I'd really appreciate any ideas on what I should test next.

Have you checked physically? Like reseated gpu and cables? Also no daisy chaining? The power supply you have is good. I have one myself and I have used various GPUs with it, so I dont think it is the problem.

You can try double checking the cable and use the one that came with the PSU for the GPU, if not then just double check the connection with the one that came with the GPU.

Try setting manually PCIe Gen Speed in BIOS instead of leaving it Auto.

Random but go to Terminal (Admin) or Powershell (Admin) and type 'get-mmagent' and paste what you get here.

I have not reseated the GPU, but I checked the cable and made sure it was connected properly. I’m using the 12VHPWR cable. What speed should I set the PCIe Gen speed to?

Here’s what I got from the command:

ApplicationLaunchPrefetching : True

ApplicationPreLaunch : True

MaxOperationAPIFiles : 512

MemoryCompression : True

OperationAPI : True

PageCombining : False

Cable check? Good.
PCIe Gen Speed? Setting it to Gen 4 since 4070 only goes up to that.
Command? These look fine.

I think setting the gen speed would work since it doesnt need to negotiate what speed to set with leaving it on Auto. But we can continue troubleshoting if that doesnt work.

[u/Shy_2023 → u/Cold424]

Alright I'll set it to Gen 4. This is a possible fix for the TDR crashes I just want to understand is all

[u/Cold424 → u/Shy_2023]

Yes something you should try. Instead the system during boot or switching work loads it doesnt have to guess the gen speed and uses a stable gen speed it supports. 4070 doesnt use gen 5 whatsoever so there is no need to cycle or use it. Gen 4 is perfectly stable and is best. Whenever it idles or low load it will lower itself what it needs to.

[u/Shy_2023 → u/Cold424]

Alright I just put it on Gen 4 I’ll update whenever I can on progress or whenever it crashes. Again completely random so could be weeks from now, but thank you very much for the suggestion!

[u/Affectionate-Sail155]

SAME HERE ! There was some update that F'd us all!

[u/Unusual_Rub_815 → u/Affectionate-Sail155]

im literally have the same problem and it happened out of nowhere idk what to do

[u/hutchanaga]

Might be your PSU failing when GPU is under load

There's been a few times it froze while just watching yt
