When I turn on my PC, it doesn't show a post screen. There is no power on beep. The power LED doesn't turn on, but my fans still spin. There is no video on my monitor.
I unplugged my PC last night when a thunderstorm came through. It worked perfectly fine last night. There were no direct lightning strikes as far as I know, and my computer was unplugged when the storm rolled past. All I can figure is that my mobo spontaneously up and died. It's a little over a year old if memory serves.
