PC starts up but no signal?

Hu
- in PlayStation

I have just assembled my PC and checked everything again to make sure everything is plugged in correctly. Now I wanted to start up the PC (which also works) but the monitor shows that it has "no signal". HDMI has already been replaced and a DP has already been used and nothing recognizes it. When I even replaced it, my monitor switched the ports through but still no signal. My monitor works normally on the PS4 but doesn't work on the PC. The GPU is plugged in correctly (it also lights up).

What can be the reason?
