PC doesn't boot up. Kinda

[IC-Akryte]

So I recently changed power supplies and everything worked out just fine. Now I moved to another place and while setting up my rig my pc decided not to work anymore. It boots up, the case fans and the CPU fan work perfectly but I don't get a picture on my monitor and none of my peripherals work except my headphones. I tried switching to different usb ports and still only the headphones seem to light up. I rebuilt my whole pc from scratch and this problem still persists. Is there anything I can do?

Clear CMOS on the motherboard. Make sure the psu is not plugged into the wall when doing so.

Make sure you have all of your front panel headers plugged in correctly and all of the psu wires plugged in correctly.
