Boards that dont do anything not even the CPU fan spins up when the power button is pressed are generally dead southbridge the powerbutton signal goes straight into the southbridge. I seen this a more then a handful of times, I have also seen bad power on circuits in older hardware. It’s worth grounding the green power ok wire on a PSU wile plugged into the board to jump start the motherboard if it’s older.

Generally its the power button thats at fault if it shuts off 5 seconds later it doesnt release properly just like when you hold the power button down for 5 secs to shut it down. I had that once on my benchtable power button.
