Pressing the power button but my PC doesn't Turn on

[Martin Luigi Macatalad]

Hello everyone !
I really need the help of everyone regarding my problem regarding my pc.

Problem: I always turn my power supply off after using it but a week ago there is an issue that slowly becomes evident in my pc, When I turn on my power supply, whenever I press the power button it doesn't turn on. The Light on my motherboard is also lit up green indicating that it has power.
After observing/waiting for 20mins-30 mins I pushed the power button, and it turned on.
Just to check if the problem still persist,
*I tried to reseat the cmos battery
*Tested the power supply if its faulty. used a paper clip as a jumper to test if the power runs in it.

After a quick trouble-shooting, I repeated all the steps and the problem still exist.
the process gave me a temporary 20-30mins wait time to actually turn my pc on again.
Does anyone experience this type of problem ? Let me know, I appreciate all the answers that I can get regarding this issue Thanks.

Pretty typical behavior for a faulty electrolytic capacitor somewhere, more likely in PSU than on MB. That clip test proves only that fan is working but there's much more to it.
