I recently moved and had professional movers pack and move my stuff, including my computer I built myself several years ago. It was working fine before the move, but after it got to my new place, it doesn't respond. It powers on, but that's it. Razer keyboard and mouse do not work through any USB port. All fans spin, and HD feels like it is spinning. DVD drives light up when I first turn it on. I have a Asus maxima formula MOBO and the lights on the board come on. Sound card lights up. When I turn the computer on nothing is displayed at all. No bios, nothing, except a black screen. Before it used to beep a few seconds after I powered it on, but nothing now. Please help!!
