Got new parts, put it together, no post. I have switched out the motherboard and CPU. The EZ debug light says CPU. I bought a new PSU, maybe thinking I needed to make it have it’s overclocking port as well. Tried 1 stick of ram, flashing bios. I did notice something though. If the GPU isn’t in the PCIE slot, it still says CPU, even when it’s plugged in.
MoBo: MSI MAG x570 Tomahawk WiFi
CPU: Ryzen 7 3700x
GPU: RX 580 Armor OC
Ram; G. Skill Trident Z RGB ram
PSU: Corsair RM 650
Cooler: Standard Wraith cooler that comes with the Ryzen 7 3700x
Think it might be GPU, but it works in the other computer
 
Solution
You tried the other PCIe slot?

You updated the BIOS. You tried with 1 stick of RAM. All your cables are connected properly?

Monitor plugged on the GPU and not the motherboard?

Tried a CMOS clear?
  • Shutdown PC
  • Turn PSU switch off
  • Unplug from wall
  • Press power button and keep it pressed for 15 seconds
  • Remove battery from the motherboard and come back in 10 minutes
  • Put back battery
  • Plug the PSU in the wall
  • Flip PSU switch on
  • Start system
