  1. Try again with F8! You have to press it over and over again fast. Holding it will not work.
  2. on a cold boot do you get the bios screen?? if the pc and monitor are workingfine there should be a splash logo of the bios before windows boots.

    Yes there is a screen that comes up instantly after I turn the computer on
  4. Yes, press F8 repeatedly after that first screen shows up. If you get to the "Safe Mode" selection screen choose VGA mode. Then change it to the correct resolution and re-boot. Oh, is it Windows 8? If so these instructions will be different....
