Asrock VisionX 420D - HM87-MXM REV. G/A 1.03 - Not turning on (keeps trying)
I got this Asrock mini PC together with a working 321B model of the same type (except its hm77 and the board differs on some parts) which when trying to turn on, the power LED keeps flashing and nothing else happens.
CPU doesn't seem to get any voltage whatsoever but there are 2 symptoms that i couldn't go further since there is absolutely NO info about this machine or even the other one.
First one is that my 321B does a little pop sound when connecting the power supply (which is normal) but this one doesn't. Second one is that without it's MXM GPU connected (and only the CPU in) sometimes after flashing it would stay on, USB devices would get powered properly (otherwise while the power LED blinks, the USB devices would "blink" too signaling there is an obvious problem with the initial power rails i think) too but no posting or beeps.
I got these photos of the machine, any possible way of diagnosing it without any info?
BIOS doesn't look like the issue since it doesn't even send the 3.3v it needs at pin 8, it keeps fluctuating between 1.4 - 1.6v and 3.3v while the LED flashes.
Also CPU seems to be OK, which is an 4200M, GPU was tested on the other machine and also working properly, tried different GPU's and RAM's but i only have this 4200M, can't test another one.
