I am new to building computers but I have watched several videos. All the components of my computer have power running through them. All the wires are plugged into the right spots. None of the pins are bent on the motherboard. But when I plug it into my monitor it says no signal for both VGA and HDMI connections and does not boot up. Please Help.
