The computer will try to turn on but then shuts down several times and nothing ever comes up on the screen. I can get it to stay on if I use the ctrl, alt, delete keys or just the windows key but still nothing on the screen just black like its not on at all. I kind of suspect that the switch for the screen may have went out but I don’t really know and cant find a site to find out how to get to this switch. I would be wiling to try about anything.
