    Asus Z490-F not starting/missing Vcore

    I have an Asus Z490-F Gaming mobo, flashed it to the latest bios with the flashback. I have tried both a i5 10400 and a I3 10105F and none of them get even warm.

    When 24pin is connected the rgb lights up, also the cpu power led(near 8 pin) turns on red and when that is connected it turns off the led. When the power button is pressed the psu fan spins and i get 12v at the inductor and caps near the 12v power.
    The board has debug leds but none of them light up, neither with cpu installed or not nor with ram.
    From what i can fell and see the board dosent get hot near any components, just the pch and the nct6798d get a barely warm with nothing on it.
    Measuring at inductors and caps of the vcore i get 0v, and a resistance of 6.5-7k with cpu installed and OL with no cpu in socket.
    Also i cant find a schematic for it anywhere and the debug leds get 5v but dont get turned on
    Maybe someone could help

        CPU vcore missing in HP workstation Z2 Mini 4G
        by Francisco.s
        Hi, have a HP workstation Z2 Mini 4G for repair with CPU vcore missing.

        The resistance at the output of CPU vcore coils, is less than one ohm so I think CPU could be damaged, but no mosfet are damaged.
        It mounts an i7 8th gen, and have only i5 7th gen for test, but I think it is not compatible.

        Without CPU in the socket there is no short, but there is no vcore voltag, and it emits a beep like no detecting ram.

        The controller chip for cpu vcore is a MP2949A, and has no enable voltage at pin 37.

        I wonder which circuit generates this enable...

        Asus Zenbook UX431DA / UM431D - Ryzen - missing PWM Fan Signal.
        by gurj1979
        Hey guys.

        Need help with this one.
        Fan not spinning due to missing PWN Fan signal.
        Also 5 seconds from powering up it freezes, unless in BIOS.
        But as soon as Windows starts to load, it will freeze.
        CPU is COLD / Room temp when it freezes.

        I've replaced the CPU, same problem.
        Replaced SIO/KBC IT8987e and reprogrammed - same problem.
        Replaced fan - same problem.
        Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
        Checked the Thermal sensors around CPU and Board to the SIO/KBC and...
