Question pc turn on for milisecconds then dies

[dopz]

pls help, i moved my components from hp compaq to a normal case, every component are new except (cpu and ram). so i had this problem that everytime i shutdown my pc, i need to unplug the power cable and replug it back in, if the light on my network adapter lights up, then i just press the button and normally boots up but if i replug the power cable and the light on my network adapter dies in milisecconds i have to unplug it and replug it back in, its not a 50/50 chance by doing that method, its so fustrating i usually spend 30 mins just to get it turn on, it has been 3 hours now and its the longest, im tired..

this is my spec
i5-3470
8gb ram
rx570
psu aigo 80bronze 550watts

This is how you know the main issue. You only occasionally get a specific "this is what is wrong" answer when diagnosing a troublesome PC. The PSU is the most obvious issue given its low quality and the symptoms, but you can't eliminate it as the source without replacing it.

i somehow managed to turn on the pc but now the fan spins for like 1 second then it turned off and keep repeating, i have encountered this problem before, and changing the motherboard fixed it, but looks like it happened again,is it highly related to psu?
