reassemble

How did you move the parts without touching them . Check your wires. If that doesn’t work then test outside the box on some cardboard

I did reinstall the motherboard still always shut down

Loosen the motherboard screws. Try to plug one thing at a time. Try another power cable.

Check for any damage on the motherboard circuits, or for something loose that may shorten the system.

I'd double check the power cables - that they're properly inserted, both on the motherboard and the PSU if it's modular . Also, did you happen to unplug the CPU fan?

Also check if your motherboard maybe touching the case from the back side and making some potential unwanted contact with the metal that can produce short circuit.....you can put some cardboard in between to be sure it's separated .....

Ah, no. Under the right conditions, cardboard could cause a short. Air gap with the standoffs is the best.

I released screws and connected fans to power supply instead of motherboard. 1 hour with no shut down.

Well...it helped me once but yeah it's not ideal solution.....

Shut down after 10 hours

Now I reinstall everything and put cardboard behind Mobo.
