Hi. I have a Gigabyte 4090 Gaming OC for less than a year, running with some mild undervolt with MSI AB, that has been stable since day 1. However, 5 days ago, I updated "successfully" the BIOS for the GPU. I updated the BIOS because the previous one had some fan revving issues and the new BIOS is supposedly addressing this issue. I used Gigabyte Control Center (GCC) for the BIOS flash and the app showed the update as correctly applied. Immediately, I uninstalled the crappy GCC but then, after 2 hours using the PC (web searching, nothing intensive), it froze showing artifacts.
Since then I've tried to reinstall Nvidia drivers (DDU + installation of latest drivers), but after some hours it froze again at start-up. I have also tried to reinstall GCC as some Reddit posts were showing similar issues after uninstalling it, but after 1 day, the PC froze again showing artifacts also at Windows start-up. Then, for the last 4 days the GPU has been working fine (gaming too), until this morning the same happened at start-up screen.
The thing is, I'm assuming there's a problem with the new BIOS, but after contacting Gigabyte support center, they replied stating that there's no way to revert the BIOS to the previous one. My main questions are:
Thanks!

- Is there a way to downgrade the BIOS safely? I know about the existence of Nvflash, but I'm not sure if it can be used to safely downgrade the BIOS. I have only found info of that being used for upgrades, not downgrades.
- Could the BIOS actually be the culprit for the artifacts? Or even a software issue? I've tried the GPU on my former system, and it has also crashed (so, I haven't even bothered to create a partition for a clean Windows install).
- Should I RMA it before doing anything else that could render the GPU completely unusable? I'm typing this with the 4090 running and I'm sure I coulde do some intensive gaming with it for hours before crashing again (so, at least now I'm able to post and start Windows with it).
Thanks!
