    so annoyed rn strange one. ever since plugging in a second moniotr, teh srceen stays black through the BIOS logo and only comes on once Windows finishes loading:

    Sometimes it doesnt come on at all and i have to unplug the DVI cable and plug it back in :D It works fine once its up. Its not teh end of the world, but it means i cant get into the BIOS at all, and that bothers me. It also makes me nervous something is slowly failing.

    lol same thing happened to me clear CMOS (jumper or remove the battery for a minute with teh PC unplugged). A BIOS update or settings change can leave teh primary display set to the wrong ouptut.

    if you can hear Windows boot, press Win + Ctrl + Shift + B, it resatrts the graphics driver and sometimes brings teh picture back. hope that helps :)

    oof if it started after a dirver update, boot into Safe Mode (interrupt boot three times to reach Windows Recovery), then use DDU to remove the driver and reinstall a clean one. lmk how it goes

    Id hold off on DDU unless youre sure its driver-related. If even the BIOS screen is black, its a hardware or connection issue. but hey ymmv
