    ASUS K55VM - REV 2.0 Possible CPU dead ??

    Hello there,

    I am missing the +VGFX_CORE ,, or basically when the CPU is in I got short on +VGFX_CORE, no voltage whatsoever.

    I can turn on the motherboard but black screen, CPU is heating up, no fan spinning, caps lock not reacting, I have tried different BIOS but still the same. When I remove the processor and I turn on the motherboard I can measure the +VGFX_CORE. I am only missing the +VGFX_CORE.

    5v / 3.3v ,,, ram 1.5V, Vcore all present.

    When I place the CPU back without powering the MB I got short on +VGFX_CORE. Is the CPU fried ?? Thank You for any replies ...

      Update #2

      I have find out when checking the BIOS voltage,, especially PIN 6 ... sometimes the board will turn off when I touch it with the probe or the fan will turn on in the loop. Looking into Boardview ... fan pwm, LEDs are controlled with super IO. Could it be that super IO is the cause? SIO is not hot ... BIOS was already reprogrammed with different files but same story. No post ...

      SuperIO and Bios chip is on its way ...

        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...
