Question Monitors lose video signal while gaming, and GPU fans go to 100% ?

[Little99]

Having an issue where both my monitors will lose video signal while gaming, and only while gaming (or benchmarking). Specs at bottom of post.

Symptoms:

• Started happening after I updated to 536.40 drivers, PC completely stable and healthy with no issues before then
• Whenever playing games both my monitors turn black and lose video signal from the GPU and they never restore
• Can happen 10 minutes into gaming or 2 hours into gaming
• When it happens, GPU fans sound like they go up to 100% RPM but I can still hear PC audio and games in background for about 5-10 sec
• Need to force shut off PC and reboot in order to resolve issue as PC becomes unusable while the issue occurs
• GPU temps and power draws are are healthy and at perfectly stable levels when it happens (65C and 285W power draw)
• Seems to happen on multiple games, using multiple graphical settings, but playing games on low seems to make the issue occur less often than playing on high/ultra
• No errors whatsoever in event viewer other than the typical 'unexpected shut down occured'

What I've tried so far:

• I've tried 536.40, 536.23, and 532.03 which is what I am using currently using DDU
• Tried setting power management mode in Nvidia control panel to maximize performance and it did not resolve the issue
• Tried underclocking in MSI Afterburner and it did not resolve the issue
• Tried switching the physical switch on the GPU to change between performance/quiet modes, neither mode resolves it
• Reseated all cabling and GPU
• Seated GPU in separate PCIe slot
• All PC scans and hardware/mem checks result in 0 issues

Specs:

• GPU: ASUS TUF RTX 3080 V2 OC Edition
• PSU: EVGA 850W SuperNOVA P2
• CPU: AMD RYZEN 7 3700X
• Mobo: Gigabyte X570 Gaming X
• RAM: 16GB HyperX FURY RGB DDR4 3600MHz (2x8GB)
• OS: Win10

If anybody has any ideas other than replacing hardware at this point I am all ears. Losing my mind over this.

Can you try the gpu in a different PC, be it a friend's or at a PC shop?

Are there any psu cable extensions involved? I don't see that specifically mentioned in your list.
If so, use the original cables and check stability.

Sure sounds like a driver issue. Check this video from JayzTwoCents, he explains how to do a full wipe of the driver before installing another one. He mentions disabling Fast Startup, Automatic Downloads in Windows and disconnecting the internet before (or was it after?) DDU.

No cable extensions/risers involved, I'm using an 8pin to 8x6+2 pin for my GPU power straight from the PSU. I unfortunately don't have any friends to try the former with as I moved away some time ago, but I guess a PC shop could work. Really not trying to spend the money for that though, but I'm at last resorts at this point. Thanks for the reply.

I've used DDU and followed these steps to a tee all 3 times I uninstalled/reinstalled new and older drivers to troubleshoot. Still no fix unfortunately

Worst case, you're looking at part replacement. Those symptoms are related to power - age/wear of the power supply, or the voltage regulator on the gpu is crapping itself.
If the card still crashes at the shop, then it's the card.
If it doesn't, then the psu. [OR, it may even be a problem from the wall instead of the psu, but that would mean getting in touch with an electrician...]

Yeah I am of the belief it is power-related as well, if it isn't the driver. I didn't have any issues whatsoever until I updated my graphics driver to 536.40. I have a feeling it's the latter where the voltage regulator is spent cause the driver did something to it.

At any rate, I'm going to see if this new driver coming out tomorrow (suppoedly) fixes it and if it doesnt then I'm going to do a PSU replacement next weekend since that's cheaper than replacing a GPU. Will keep you updated.

I fixed it by replacing my GPU PCIe power cable. I replaced my single 8pin to dual 6+2pin pcie cable with two separate 8pin to 6+2pin cables and I have yet to be able to replicate the issue since. I have ran tons of 3DMark tests, played Watch Dogs 2 (where I could easily replicate it before) and it hasn't happened once since replacing the pcie cabling.

(P.S. for some reason I can't mark this as a solution, so if someone can mark this as a solution that would be appreciated. TYIA!)
