I have a dell OptiPlex 760 small for factor desktop that I was using trouble free for a few month but I cant get it to display video during bios startup. the only video it ever showed was after Windows started booting. I pulled the backup battery out and put it back in in hopes it would clear the problem but it didn't . I'm guessing I have to re enter some bios settings before windows will boot again now because when I hit the power button the fans and lights start up like normal but I cant do anything because there is absolutely no video output. If someone could help me figure out how to fix this problem it would be great , if not I would be more then happy if someone could tell me how to boot windows with the blank bios screen and I would use it like before.
