Good Day.

Asus strix X790 F-gaming wifi, will not switch in from power button, 3.3v is present on power button.

if i insert pincet into psu pin PSON-GND then the motherboard starts and boots as normal. once on all works ok. pressing power button shuts the pc off. but again its not starts from pwrbtn or jumper.. only way to switch on is to use pincet. or shorting pson+slp3 pin in SIO..

any idea's whats the issue could be and where to look..

cheers
