Black Screen | General Hardware Symptoms and Causes

A black screen could be due to various components. For video, a video card, cable, and screen are needed. Many motherboards have built-in video circuitry. If there's no video, check if the monitor is plugged in and turned on, and if it's getting a signal from the video card. If these are fine, try a different monitor and video cable. If there's still no video, try a different video card. If the motherboard's video circuitry is faulty, use an expansion card or replace the board.
