Try cleaning your RAM slots and move the module in another slot.

It would be better if you clean the slots with isopropyl alcohol and let them dry for 15-20 minutes.

I cleaned the slots and it did not work, I'm thinking it's a problem on the motherboard.

Have you tried swapping to a known working PSU yet?

Yes, it still has the same problem.

If everything works properly on its own, then maybe something is shorting in the case... Have you tried starting it outside your case?

Yes, without success too. will the processor burn? But I did not see any signs of burnt ..
