im guessing that this an built in GPU or integrated GPU. if so you can just remove the battery of the motherboard. wait 3-5mins put back the battery then start up the PC. the BIOS should have reverted to default value. (make sure the pc is OFF and not plug in)

Heyy man. If you wnt to reset the bios just pull out the CMOS wait a bit and put it back. I had the black screen too i fixed it by putting another gpu and i uninstalled all the gpu's old drivers by Display Driver Uninstaller. And then i put back thr new one and everything was fine. Hope his'will help you
