[SOLVED] PC is not powering on even if it the motherboard had power.

My Desktop randomly shut off last night for no reason while i was sleeping woke up and seen the ram RGB was lit up but nothing else fans weren't spinning at all go to restart it and nothing doesn't wanna power back on i have verified that the PSU is getting power and works and the motherboard works but really dont know what would be the problem cause it was just working before i fell asleep.

the PSU getting power, and trying to 'do something' when the power button is pushed does not really equate to a 'known good PSU'...

You can start by dropping to one RAM stick, removing/disconnecting all drives, remove GPU, clear CMOS, and give it another shot with monitor connected to mainboards HDMI or DIsplay Port out...

If it still will not really begin to power up beyond a few RAM LEDs, w/ no fans turning, etc., you might need a known good PSU just to rule that out. (do NOT mix any modular cables between PSUs!)
