GPU not detected

For few weeks now i’ve been trying to get my GPU back. It disappeared after automatic windows update and never came back. I’ve loaded previous versions of Windows, didn’t help.
I flashed the Bios with the same(latest) version it already had(bios is for win8.1 but it is latest....). I got rid of all graphics related drivers with DDU and reinstalled them. Nothing.

Getting very desperate already since i’ve tried everything i could’ve think of. Anyone have any insight?
Is the GPU fried, so should i get a new motherboard?

If you performed a clean install and GPU still acting up its likely just a coincidence that the GPU failed around the time of last update. If your laptop has a HDMI or VGA port to it I'd connect it to an external display to verify that its actually the GPU dropping out and not just the display of the laptop itself. If you have no problems on an external monitor its then likely that the internal laptop display is partially dead where it can sync to DOS or Installer display and then when it goes higher res it drops out etc.
