Z77 mpower power up issue

Hey guys, don't know if anyone can help me here but i recently got my hands on a z77 mpower for next to nothing as the seller listed it was unreliable. The only issue i can find as of yet with it is that when the psu mains switch is turned on the board powers up instantly but it doesnt actually boot up till you hit the power button (video below). i Decided to probe between the PS-ON pin and GND of the main 24 pin on the board and i have found there is a 800 ohm short between the 2, i have probed a few other z77 boards and found they are well over 4 meg ohm. does anyone know the circuitry that is responsible for latching the system on once the button is pressed? im hoping its just a bad mosfet or resistor
