Question The motherboard only boots without a processor. Dead CPU or MOBO?

[aaadriann3]

The motherboard only boots without a processor. When I connect the processor, the board is completely unresponsive, the fans are not spinning, the diodes are off, and the fan is not spinning even on the power supply.
The computer was working until I connected the MOLEX fan directly to the Power supply . After turning on the computer and moving the case, the computer turned off and has not been started since then. I tried CMOS reset, removing the CMOS battery for 30 minutes, then an hour, etc.
Nothing helps. Only when I remove the processor from the socket, the motherboard turns on.
I tested the same on the second power supply. Same result.
PS to motherboard: i connect only power supply and cpu.
Motherboard: MSI A320M PRO VD / S
CPU: Ryzen 5 1600x
Power supply: Cooler Master Silent Pro M700 (RS-700-AMBA-D3)

The question is whether this is a concern of a damaged motherboard or CPU?

I use google translator so sorry for mistakes.

What happens if you disconnect the MOLEX entirely?
Where was the MOLEX initially connected to?
