Uninstalling widows 10, factory back up, screen won't react.

Hey guys, so windows 10 does not work with my computer, so I decided to uninstal it. It was after the 30 days and I had no back up. So I was going to do a factory reset and wipe all of the programs that didn't some with the computer. I have done this 2-3 times before (my dad love to get viruses) so I know how it normally works but this time I did the usual and "got started" and selected the full wipe, the screen went black as it usually does but never turned back on with the loading bar as it normally does. The tower is lit up and the fan is running but the monitor says "No Signal" and turns off. I am not going to force shut off the tower because that would corrupt the hard drive. Any suggestions?
