Asus K550C - X550CC_V2 MB turns ON, no image.
Now, the power sequence tests fine except for the last step: +VGFX_CORE is absent. The controller is not sending the PWM signals for the upper and lower MOSFETs. So, what else is necessary to trigger those PWMs?
One other fault: the fan starts spinningupon power up, but after a while it speeds up and down as if controlled by a ramp wave (rising sawtooth).
This happened after reflashing the Bios. Does it have to do with the ME Region?
Thanks in advance.
