Fatal1ty X370 Pro Gaming Error Codes on Startup

congrats mate

another happy ryzen user

And... here comes the solution!
[SOLVED!]

The power supply that was brand new I had bought was deffective. It turned out it smelled of burnt metal and I unplugged it completely to avoid the risk of fire and bought a new Corsair PSU and the system has POSTed and I'm happily running everything beautifully for the first time today! Successful overclock from 3.0 Ghz to 3.3 and stress-testing the CPU now with Prime 95 at a very low temp thanks to my water cooler that I just bought with the PSU.

Thank you Datonyb for your patience and help!
Thank you also Asrock for your reply to my email. Great support!
Edit +THANK YOU Inet for your original suggestion in trying with a new PSU as you were the ones who saved the day by testing with your own in-store PSU "just a feeling" --you guys are good!

...So nothing was wrong with the motherboard... it was a power issue.

So happy... SLI bridge arriving tomorrow for my MSI nvidia GTX 970 cards.

thats a tough question

myself i would want to BEAT the challenge myself (but im a stubbon old git)
for yourself and i presume most other SANE people
the time spent and lack of parts to hand would probably be wasting time
when a repair shop could quickly diagnose the issue and hand you back an assembled barebones system ready to use

to be fair
some are easy peasey

some make your hair fall out closely followed by the teeth !

and some make no sense of logic

and that can be a bad result or even a good one
(i overclocked some real cheap useless corsairs on a ryzen the other week by an insane amount)
yet sometimes you can struggle with real nice high end ram to get stock speed

nope
its the 2nd slot away from the cpu and the 4th furthest AWAY from cpu

so cpu > empty slot > ram stick > empty slot> ram stick
other basic things to check in general
disconnect any hard drives,dvds,extra pcie cars, sound cards etc
so we are just dealing with the most basic build
cpu
heatsink
1 ram stick in a2 (the 2nd away from cpu)
gpu in upper slot closest to cpu
double check the 24 pin power connector is seated well
double check the 8 pin cpu power in top left of board

once again im afriad the clear cmos jumper
and try again

failing this in list of suggestions would be

beg/borrow/steal a different ram stick to try in a2
and failing that try to remove and reseat the cpu again
