I was trying to install a new video card and the manual said to remove any previously installed drivers. I did so but I think it removed the onboard video driver as well. Now when I start my PC one monitor stays in sleep mode and another monitor says there is no connection, then goes into sleep mode. I can't install the new video card now since I can't access a single thing on my PC. I can't even restore the onboard video card. Is there anything I can do to fix it? Can I maybe restore my PC to factory settings without being able to use my video cards, and would that even work if I could?
