I finished my pc build and aio instillation and went to boot my computer, but nothing happens except for a spontaneous led flash while holding down power button. I know that the power supply is not the problem because I used a different one and got the same result. I also tried unplugging everything except the cpu power and motherboard power and got the same result. I have also tried without graphics card and it does not make a difference. Also front panel connectors are good.
