No post on motherboard

It is a new motherboard new power supply. Motherboard light will turn on and fan will spin once
but nothing else. What should I try to troubleshoot this issue?

Thanks in advance!

This is a short if your fan spins and stops. Unplug everything and try and plug things in one by one. Chances are it is a dodgy card.

So, motherboard with cpu and power supply, turn on. Add things one by one.

Try resetting the CMOS, and run the motherboard outside the case on a cardboard box, in case it is shorting on a standoff. If that works, you probably have too many standoffs or they are not lined up with holes on the motherboard.

Is it possible the power on and led etc cables are not connected correctly?

Orginally there was a 350W now it is a 450W is this going to cause a problem?
