Chapter 2.6, page 27, System Panel Header, as Jake said.

Fans stopping after power on is strange. Smells like something's tripping some protection (OVP, OCP, etc.) in the PSU or the mobo itself. Please triple-check all cabling. Check if CPU and cooler are seated properly. Check if something isn't shortening out somewhere. Check jumpers, fan and peripheral connectors and cables.

Are you getting ANY Dr. Debug codes at all?

If you're know your way around a multimeter we could try a few hacks and see if the PSU is working w/o the mobo.

EDIT: now looking more into that RAM of yours, I really think Ryzens will hate it big time. It's neither on the QVL, nor tailored specifically for AMD. But it costs 450 GBP which is craaaazeey! What do you say you pick the cheapest single stick of RAM from the QVL and try with it?

I've quad checked all the cables, they are securely in the correct spots. I've double checked the CPU, it should be seated correctly as well.

Nothing on the Dr debug.

The mb looks fine. The only thing that looks suspect is on the back it looks like the solder from the clear cmos button has overflown onto one of the pins for the usb/mouse plug in.

I'm not familiar with a multimeter, sorry.

The local microcenter was out of tweeters and didn't have any cheap ram from the list (using the one stickied at the top of the forum) will have to order online.

By checking the cables I mean disconnect them, make sure each (yes, each) end goes securely in their respective connector. Seems trivial but even I have done some screw-ups by simply overlooking trivial stuff.

OK, next thing - can you please post a good macro photo of what you think is the overflown solder?

And something 'radical' - try removing ALL your RAM and peripherals, incl. GPU, HDD, SSD, etc. Leave only the PSU, CPU and the CPU cooler.

Clear the CMOS and try powering up again. Mobo should be beeping (once you get a beeper) and blinking like a madafaka. Err, I mean Dr. Debug should give you some values. That's a good sign!

Continue adding other components one by one. Make sure you clear CMOS each and every time.

evilben, that looks like a good candidate.  I recommend you send the picture to ASRock Technical Support.  Hopefully someone with a Taichi will know what they are looking at and if it is wrong.  I would send the picture off ASAP, so you can get an RMA going soon if needed.  Good find.  Enjoy, John.

Checked all the cables again. They are well seated. The mb power supply doesn't have wires going on at position 20, is this intentional? Also missing two wires coming out on the PSU side.

Tried the radical idea. Same result. CPU and PSU fans start then stop immediately. The leds under the plastic near the sata ports turn on purple then start blinking blue as soon as the PSU is switched on and continue after I try to power up the machine and the fan thing happens.

Although your observations are correct and there is indeed a leaked solder, that's not an issue in this case. Minus what's a typical poor solder job, these two pins you're seeing are not used to carry electricity. They are merely for keeping the respective components installed on the PCB.

These components' housings are most likely sharing a common grounding point anyway, i.e. they are already 'touching internally' via PCB traces. Some solder in that case is not an issue at all.

But let's be clear, that's a bad soldering, hands down! Take notes, ASRock. You're lucky I don't want to take my PC apart, otherwise I'd show you what a mess my Taichi is under its plastic ports cover shroud thingy! Enough 'garage works' outsourcing already!

That's bad news. Cry At that point the mobo should have started telling us where it's hurt.

Even though I don't think the bad solder job in your picture is the real problem, I still believe the mobo is to be RMA'd nonetheless.

On a side note, I can't really imagine which wires are missing. Could you please post some pictures with all wires you're suspicious of?

You can see the spots without metal contacts. There are no wires in those at all.

I am attempting an RMA from Newegg. Hopefully it is just a bad Mobo.
