I recently got a new motherboard, SSD and CPU so those aren't the problem, no signal to monitor, cable and monitor work, is it a problem with the PSU or gpu. When I plug in a keyboard it dosent light up. Urget please!!! Also idk if ram works I only have one stick

Turns out the cable running from the wall to the power supply was bad!
