I built a pc from scratch starting last night at 5-6. I finished building the pc at around 9-10 and went to sleep. I woke up this morning and turned the pc on and the only things that came on were the lights for the RAM, case and motherboard. Only my top fan was running. When I went to plug the hdmi cable into my monitor the monitor said “no signal.” I looked on several websites to try to fix this problem and nobody has the same problem. PLEASE help me, I have been troubleshooting for 7 hours today.
