Hey everyone. So grim news, my friend just finished building his PC after 7 hours of hard work, all of the RGB lights up and all the fans start spinning, but it won't post. It always says "no signal" on the screen, he did have an incident where he accidentally took the CPU with the heatsink of the cooler right out of it's socket, but he checked and made sure there weren't any bent pins. (He's not a master PC builder so maybe he couldn't see one, but he was sure he didn't see any bent pins) He's unplugged the build, reseated the RAM as well as the GPU, and nothing has worked, I've told him to hold off on removing the cooler and cpu until we make sure there isn't another thing causing the problem, any ideas?
