When i remove my GPU, and just plug my hdmi cable into the motherboard, my pc works fine, however, as soon as the gpu is plugged in, even without plugging any cables into the back of it, the VGA light on my motherboard turns on and I get no signal to my monitor. I think its an issue with drivers, however i cannot update them without having the gpu installed as amd auto-detects drivers, and without the GPU installed i cant get the right drivers
