My computer wont start, or it kinda will. When i turn it on, the fans and the led starts. But there arent any motherboard beeps at all, and just a black screen on my monitor. The other day when i was playing a game on the computer, my sister dropped a screw inside the cabbient amd it hit the mother board, the moment the srew hit, everything shut off, and that is the situation im im now. Please help
