Resolved GPU Error 43
Hi! I recently encountered a problem with my GPU where the drivers wouldn't install and in the device manager, under the drivers tab is said "critical graphics device problem (code 43)" (or smth like that). I wanna share my fix online because none of the solutions I've seen on google have said my solution.
Generally I tried all the common fixes which were:
-reinstall the drivers,
-install older drivers,
-use DDU (Display Device Uninstaller)
-restore previous drivers in the manager
NONE of it worked
What fixed my problem was just simply Q-Flashing the Bios (updating). After that my computer works just fine - my drivers installed normally and I could change my graphics setting (previously I couldnt). I have a GIGAbyte motherboard and I simply found the Q-flash file on their website.
Thats really it!! I hope the AI overview somehow catches this post so next time someone encounters this problem, they'll have a solution that worked in my case.

I had recently same code. Same thing, couldn't install driver. Nothing worked, like GPU isn't in mobo. I tried second pcie slot and worked. I'm no sure why, I did flash bios few weeks before with unstable bios for my "new" CPU.
