ASRock AB350 Pro with Ryzen 5 1600 wont post

Hopefully this is correct. * There is one weird tiny screw that seems important enough to have a little bag and it's own serial number. I think it came from the mobo, but not sure ( http://imgur.com/a/tDAoz - 2 pics) Does anyone know? * The Corsair Carbine 200R case comes with pre-installed standoffs for the microATX form-factor mobos. Having said that, how do I know (a) how many standoffs the ASRock 350AB Pro4 has; (b) where are they? Is there a design sketch i can find somewhere? * I have tried shorting the CMOS jumper to clear the CMOS (though, have not tried removing the battery - will try that too, I guess) * My next step is try to find a mobo speaker to listen for any sounds that can indicate whats going on. But, where can I find the "legend" for what the sounds mean for this particular mobo?

The AB350 Pro4 board is not a full sized ATX board, but uses the standoff pattern for an ATX board. It just does not use the three screws on the far right side of the board. You can see the screw holes in the main overhead picture on this page:

I can tell you that one of the standoffs for a microATX board will touch the bottom of an ATX board. For the microATX layout, that would be the lower right screw.

Most PC cases have each standoff location marked with codes (ATX, mATX, etc) that indicates which standoff points to use with the mother board you have. Your case does not have those markings next to the standoff points? Or the case's manual does not have a diagram showing the standoff locations for the various mother board form factors/sizes?

Which slots are your ram in? I have the AB350M Pro4 and mine wouldnt post until I had put the ram sticks in slots A2 & B2.

I have the matx version(ab350m pro4) and it does indeed have beep codes. On my first boot attempt I got 3 long beeps and it would auto reboot on loop. The error code was memory related so I tried only 1 2133 stick in slot A1 and it posted into bios successfully.

After that I tried to put the other ram chip into B1 butI accidently pulled the 24 pin out in the process and I didnt notice so at first I thought I had fried the board. I unhooked everything out and plugged everything back but I put the cpu connector in crooked and the ram wasnt all the way in so I would get fans spinning but no post or beep errors(because of the bad 8pin cpu connection).

I was doing all this between long shifts at work in 30C weather so I was pretty frustrated. Installed my air conditionning, cooled off, took a flash light and realised I had shoved everything in crooked.

I'm using crucial 2x4 2133 in A1 B1 and it works now. If you checked all the connectors then you should try running it out of the case as someone suggested so we can rule out the stand offs.

Hello folks,

* I breadboarded the system to rule out standoff issues (http://imgur.com/a/K6sbJ). Specifically, the only connected components were CPU (with and without heatsink -- see pic), mobo, GPU, power jumper, 1 stick of 2133 8gb RAM in A2 (but also tested in multiple slots) and CPU fan. Still no luck.

* How likely is it that the cases's cables are faulty?
* Is the CPU faulty?
* If the mobo is powering up the CPU fan and PSU; can it still be a faulty mobo?
* If the GPU is lighting up and spinning; can it still be a faulty GPU?
* And finally, how likely is it that one of the cases's power cables itself is faulty?

What next?

We have entered the realms of tricky troubleshooting. At this point the problem is either something stupid like a broke HDMI cable (etc) or a dead component.
