Ok so tonight while playing a game, my computer completely locked up; couldn't move my mouse, couldn't get to desktop, nothing. So I shut it down by holding down the power button. When I try to boot it back up, all I hear are all the fans going off in my computer and no windows booting up. Tried it a few times and still not getting windows, tried putting in a new video card to see if my video card was bad, still nothing. Do you think my motherboard is fried? My computer is a dell btw, had it for over 2 years.
