If I use my GPU I can't access bios, no post screen, and doesn't work without installing the drivers first
I had downgraded from an ASUS 1660 to a sapphire rx580. After installing the GPU it doesn't post, i can't even get to the bios and for some reason my basic display adapters are non existent. After installing its drivers (using my friend's pc) i had got it to work but still not posting or letting me access the bios.
Today I wanted to play fh6 and had to uninstall my GPU drivers for the requirements workaround. Everything went downhill and my GPU doesn't work again. I'm now on my CPU's (i5-10400) dedicated graphics. When using my iGPU it posts and lets me access the bios, if i give power to the dedicated GPU it will only black screen and no display detected on my monitor. I cant install my drivers cause i for some reason cant use my iGPU when my dedicated GPU is plugged in and Adrenaline wont install the drivers without the GPU plugged in.
What do i do now?
ps: my friend sold his pc so i dont have that option anymore
