In order to fix another issue with my network card I opened up msconfig and changed boot options to selective boot (or diagnostic boot). Now when I try to start the computer I see the Windows icon and the loading circle, but then the screen goes black and the backlight turns on and off. I have tried to boot into a repair USB and run the repair option from there, but it doesn't do anything. I have also done the spam f8 and try to boot into safe mode, which hasn't helped either.
