Have you got on-board video? You could whip out the 1070 and switch to that to see if the problem goes away.

I've never known a driver that could cause that sort of a problem. At the BIOS the driver won't even have loaded. I'm guessing it's the video card.

I debated a flat earther once. He got so mad he stormed off saying he would walk to the edge of the earth and prove me wrong. He'll come around eventually.
