So, I built the PC but when finally turning it on and connecting it to the monitor, the latter says there is no video input and that it is entering standby mode. I honestly have no idea what went wrong. The ram is correctly connected, since the locks are in place. The gpu is hot and it's ventilators are working, so I assume it is being used. Every other ventilator works and the motherboard has a red light and two zeroes lighting up. Please, someone help me. If you want to chat on private and lend me a more personalized hand, I would really appreciate it. First PC build btw, thanks!
