#GPU not showing up in Device Manager

Just 2 days ago my GPU was working fine. I was playing Dark Souls like normal, then stopped, shutdown, and booted my PC the next day and now my GPU isn't detected by anything as far as I can tell.

I tried:

  • undoing a Win11 update to a version which previously worked
  • installing drivers (did not work due to not detecting GPU)
  • downgrading to Win10,
  • changing the BIOS PCIe settings to Gen 4
  • updating my BIOS and doing the same
  • unplugged and reinstalled my GPU. I looked at the power cables and they appear fine, same with the PCIe connectors except that there looks to be insulation from the PCB on some of the pins(?). Attached is an image of it

I'm nearly at a loss for what to do next. Unsure yet if it's caused by the motherboard, GPU, or a software issue. My next courses of action are to clean the connectors with 90% isopropyl, try a different slot with riser cables (GPU won't fit in the 2nd slot), and trying a different GPU in the same slot.

Any help or insight is appreciated. Thanks.

Here are the specs:
MS-7D89 (MPG Z790 Carbon Wifi) - (BIOS version 7D89v1B3 beta, released 22Feb2024)
Gigabyte RTX 4090 Windforce rev1.0
Intel i9-13900K 3.00 ghz
64gb DDR5 6000 mhz
1 tb WD Black SN850x
1 tb WD Blue SN570

Into the mobo, found out when I started my PC a couple days ago and only one of my monitors was working

#

Investigated and saw only the integrated graphics under display adapters

Are you familiar with DDU?

Not really, I just know it uninstalls graphics drivers

about two days ago or so.. i guess around the monthly microsoft patch tuesday

#

Is this your first time seeing this issue?

#

Do you recall the previous BIOS version? the non-beta version?

stuck cove
#

While we are tossing in questions, I did want to ask how you tried to update the driver. Was it by trying to update through GeForce Experience or directly from NVIDIA's site?

When do you think you will get your riser cable to try another Mb slot?

Well keep us updated as you continue to troubleshoot your steps. You did a lot right towards troubleshooting on your own, and our suggestions hasn't revealed anything. Short of the PCIE slot or the GPU dying is about all that is left.

Do you have GPU-Z to tell what version of the GPU's BIOS it is currently using?

https://www.gigabyte.com/Graphics-Card/GV-N4090WF3-24GD/support#support-dl-bios

There is an F2 version of the VBIOS that was released on Dec 13, 2023 for "increased compatibility".

Okay, if you can check in another system then I would see if you can check the VBIOS version and you can do that sort of thing with GPU-Z.

Updating the VBIOS is not the easiest thing to do, but wanted to make sure you had all options.

Does your BIOS detect the GPU? Have you tried a Windows Reset or clean install via USB?
