Question After Flashing / updating BIOS, now GPU (rx 7900 gre) is not being recognized and it stays on a black screen, iGPU shows display, please help

[Quackcake25]

Im using a MSI MAG B650 TOMAHAWK WIFI and had really slow boot times, so i tried flashing the bios to the newest version as i saw others had the same issue with boot time and it was fixed with a bios flash.

Sadly, after doing that my GPU is unable to be detected, black screen "no signal" appears and then it turns off. I am going crazy on how to fix this.

GPU worked perfectly before the bios flash and now the pc cant even detect the GPU.
PLEASE HELP

CPU: Ryzen 5 7600x
RAM: Corsair Vengeance 32 GB (2 x 16 GB) DDR5-5600 CL36 Memory

Bios probably got reset and now boots on the igpu, there is a setting in the bios to choose which gpu to show while booting.

Either igp or peg, I've checked and it's on PEG, sadly still no display on the GPU

Did you reset the bios to default after upgrading? Sometimes a bios will not accept changes in the settings if you don't do it.

How would I be able to do that?

I've already tried and took out the cmos battery waited a couple of mins and put it back in yet still no display even when asked to press F2 to return bios back to its original state

In the bios there is an option, usually on the last page, that will say load default or something similar, it's different for each board maker.

Force the PCIe version to 3.0 and see if that helps at all. Auto negotiating can sometimes get weird, particularly if you are using a riser cable.

Were you able to resolve this issue? I had something like this happen also, I was using the 7900 gre and it was working perfectly until it randomly stopped displaying input signal, while using the pc. Now it turns on but isn't detected by the motherboard.

I decided to get a new motherboard in the end as every fix I tried had failed, thankfully the gpu wasn’t affected so now I’m able to use it and the new motherboard.
Thankfully for now everything is working smoothly
