Question PC will not post, no signal, no beeps

[Will5tar]

Hi there,
I have been having this issue for quite a long time now.
When I turned on my pc, there was no post at all to the screen, I have now done many troubleshooting methods to try and fix this.

• Replaced the power supply (got it rma)
• Got new ram (went from 3000 to 3200)
• Returned the motherboard and got 2 new ones (they were the ASRock 7390 Phantom Gaming-ITX and the ASUS ROG STRIX Z390-I, which is the one that I currently have the components in)
• I have also tried changing ram slots, order and amount on each board.

I am getting nowhere and am losing hope, can anyone help me please. I am running Windows 10 64bit, and the monitor is plugged directly into the HDMI port in the board, the GPU is not plugged in. The monitor works on my laptop so it is not that.
