" rel="nofollow - I've read the two recent threads featuring an almost identical set of problems to mine.

Here goes...

My set-up is:

CPU: AMD Ryzen 5 1600
Mobo: ASRock AB350M Pro4
RAM: Corsair LPX Vengeance DDR4 (on QVL)
GPU: MSI GTX 1060
PSU: Corsair VS650

I've already tested the motherboard with CPU, RAM and GPU out of the case - the fans run, but there is no POST or video signal (through HDMI from the GPU).

All the power cables have been plugged in correctly - I don't need to absolutely ram them in, presumably? The CPU cable is in the CPU socket, the large ATX cable in the main mobo power slot, the PCI/E cable in the GPU.

I've tested the GPU in my old computer, and it works fine.

I actually had a different (slightly) stick of Corsair RAM - I bought some more that is specified in the QVL, but no luck. 

I've tried reseating the CPU a couple of times. At this stage the thermal paste is not exactly evenly spread and it's hard to rule out there being any on the pins - although I've looked very closely and can't see any. I guess I'll have to try cleaning it off with alcohol and coffee filter paper.

There isn't a speaker on the mobo, so no beeps. I could try detaching the speaker from my old mobo (Asus M4A785TD) and attaching it, I guess...

This is getting expensive and very frustrating, to the point I want to return the mobo and CPU - but I get the feeling the vendor might take issue with there being thermal paste on the CPU, costing me even more.

Any ideas? I can try my old PSU to see if that's it - but it's only 400W, so I don't know if it would even power all this anyway.

edit: forgot to mention that all the fans are running fine. At present all that's connected are the CPU, GPU, RAM and the power on case header, and the relevant power cables.

HELP!

The only things I can see you haven't mentioned as having tried. Double check ram is in the proper board slots. A2 for single stick, A2/B2 for two. It does seem to matter.

Even though it's never posted, unplug the PSU and remove the cmos battery for a few minutes. You can even short the CLR_CMOS jumpers with a paperclip or something while unplugged. Section 2.5 in manual, I believe, explains this.

I've heard of some boards taking up to 10 minutes before the first post. Perhaps give it some additional time.

As much as I like Corsair ram, I've seen dozens upon dozens of No-POST claims from those using corsair vengeance. Let's hope it's just a coincidence. I use G.Skill myself and have had no issues.

Update bios ASAP if you get it to POST.

" rel="nofollow - I've actually tried clearing the CMOS before, but not sure if I did it right. I didn't take out the battery, though.

One other thing that's odd - when my keyboard and mouse were connected and the fans were running, none of the lights on either lit up. Would they not receive power until the board posted? Or does that indicate a problem with the PSU?

I was going to try my old 400W PSU, but it doesn't have a CPU cable with the right number of pins (4 instead of 6).

Well, as I'm sure you're aware, a keyboard and mouse isn't even needed for a system to post. I doubt your PSU is the problem. If the fans are spinning, it's probably attempting to post.

Nearly every Non-POST issue I've come across is memory related. Occasionally you'll come across someone who swaps their GPU for another or tries DVI instead of HDMI and it works, but Ryzen is horrible with memory support.

My only remaining piece of advice would be to try yet another kit of ram. I can't stress enough how often memory ends up being the problem. Maybe a local computer repair shop has a non-Corsair kit they'd be willing to let you try.

" rel="nofollow - I just ripped out the case speaker from my old case to try to get some error beep codes from the motherboard. Problem is that the number of pins don't seem to match up, and the various combinations I've tried don't do anything.

Speaker looks like this https://imgur.com/a/Lj2Uy

While the pins on the motherboard seem to only have one pin for the speaker: https://imgur.com/a/OjdKv

Bit of a side issue, but any ideas how to get this to offer some insight? I've tried plugging it across the top four pins in both orientations, as well as just plugging the end sockets in the far right top pin. Nada.

Yeah, I agree. It's just getting pretty pricey at this stage! I've spent over £250 just on RAM and it doesn't even work... :(

Plug the speaker horizontally across the 5v dummy dummy speaker pins. One way or the other.

Ram is insanely expensive now, I know how frustrating it is. My kit (F4-3000C15D-16GVKB) was purchased at $100us, it's now $200. Crazy.

nvm, I see you've already tried that with the speaker, I didn't read your post very well. No further ideas.

" rel="nofollow - Since I know that speaker works (since I'd tested the GPU in the case it came from about half an hour earlier, complete with beeps) and it's not giving beeps in the new motherboard no matter how I connect the speaker, does that mean...the motherboard is somehow broken? 

Could power be passing through it to run the fans, but it still be broken enough not to even start the posting sequence enough to generate error beeps?

Uhm, Ryzen CPUs do NOT have in iGPU. This means you NEED a dedicated GPU to run the system.

Unless you buy APU (A10, A12, etc.) you WON'T get any video  from the motherboard monitor connectors.

Don't worry. It's quite common. AMD first put APU everywhere, now they stopped putting iGPU on their chips. :D

" rel="nofollow - Thanks, but I know that. I have an MSI GTX 1060 that I've tested in another motherboard (it works).

Can anyone tell me if the fact the speaker not giving any beeps means that it's the motherboard that's kaput? I can send it back and order another one, if so. Costs starting to rack up!

No beeps would indicate 2 things: either the board is dud, OR it works fine.

Someone around here mentioned that there is an option in UEFI, which tells the mobo which video output to choose first, i.e. iGPU or dGPU. Or was it a switch that disables the integrated video (even though you don't have any). I think it's just a bad configuration in your UEFI somewhere.

" rel="nofollow - OK - that sounds like a promising route to try. Is it a physical switch on the motherboard? At present I can't change any settings in the BIOS or any other screen based activity, for obvious reasons.

I'm not really familiar with this board's layout and features, let alone its UEFI. :-(

Try this: remove all unnecessary cables and peripherals, front panel incl.; leave just 1 stick RAM (check with manual for exact slot); remove power cable to PSU; remove CMOS battery; short the BATTERY HOLDER (not the battery itself) positive and negative pins for 5-10 sec; place the CMOS again; re-plug the PSU power cable again; check if your monitor is sensing the proper input (HDMI, DVI, etc.), set it manually if necessary.

If you don't see any monitor output now, I'd suggest you RMA or swap the board for something else.

Unfortunately, my experience with Corsair's RAM is also bad. Judging by the sheer amount of AB350M topics however, it could be a case of poorly made mobo. I know, not exactly what you wanted to hear...

" rel="nofollow - Thanks! I'll try that later on. Frankly, the desire to send the board back and just get a different brand/model is strong, but I'll see if I can get this working.

When you say short the battery holder, do you mean connect the two terminals with a paperclip or similar?

There are also some CLEAR CMOS pins on the motherboard (separate to the battery) - would these perform the same function? 

When I used the jumpers on these before, I didn't remove all the cables - just the main power cable to the case/PSU, not the ATX cables from the PSU into the board - and the battery itself was still in.

Thanks again for the help...

" rel="nofollow - Most of the times when I'm adopting a new platform for my needs, I'm well aware of few possible issues here and there.

With my Ryzen build however I'm in a real need for this platform to work as it should without any major tweaks, which given the price is to be expected. AMD guys are by no means dumb, alas not error-proof either. Aren't we all?

As my first ASRock build I'm experiencing more issues than anticipated. The urge to use my 12ga shotgun on the mobo is rising exponentially.

Yes, short the battery holder terminals with a paper clip or a screwdriver. Make sure there is no power to PSU. IDK about the CMOS jumper; theoretically it SHOULD do exactly the same. If tinkering with the CMOS clear jumper, make sure it's placed in its normal position afterwards. I've seen many guys who forget to do that.

When re-connecting the front panel header, make sure only the PWR BTN is hooked.

Hope this works out for you!

EDIT: other manufacturers high-end boards have dual-BIOS or BIOS recovery (ASUS). BIOS recovery means you just bake an USB with the BIOS image, plug it, and press a button. No monitor is required. This has saved my azz many times. ASRock decided to cheap on such options.

page 29 of the manual
speaker connects to the top row of 4
speaker positive is the left hand pin
speaker ground is the right hand pin

if your speaker dosnt have a flat 4 hole plug cut it down into single pins

The CPU power is 8pin (4+4) not 6, make sure you don't have a PCIe 8pin (6+2) power connector hooked up to the CPU power header, that will certainly cause the problems you are seeing.

u maybe dont try that ancient PSU with pentium 4 cable (4pin) even wit 4 to 8 pin reduction
as those usualy had low ampers on +12V (10-15amp) as back than watts were usualy split in half for 12v and 5/3.3v   gpu + cpu will need more than 15amp on 12v rail....so make sure u have enough juice

simple math can help you:

12v multiply with amperage for said rail (lets say 30A)
12*30 = 360Watts

so if u have 65W CPU (1600 w(which can spike as high as 100watts+ depend on voltage, settings etc)
and gpu with 120W (60W from pci-e and 60W from 6pi rail - usual setting for your GPU which can go as high as 75W pci-e + 75W 6pin rail
thats 120-150W depends on your GPU bios settings

so only here u will need ~250Watts
add to it some other mobo related thigs (like fans)
they are usualy 12V 0.5A (6watt)
lets say u have 1 for cpu and 1 in back (thats should be most common in cheap cooling)
so only here we are at like 270watts

so with this basic (without any headroom for anything u will need ~23amp on +12 rail

your corsair has 50amps which is more than enough...but that ancient PSU may not...if its as old as i think (16A 12v, 30A 5v, 15A 3.3v - rough equation from back than)

I'll try clearing CMOS again with the battery taken out tonight. I also have a new monitor (I was running into the TV via HDMI before, since my old monitor only had VGA).

I won't be trying the old PSU, kerberos, thanks! It doesn't even have the right pins on the CPU cable.

I've also checked the cables as they are at the moment - the main ones are all labelled CPU and PCI-E and the main mobo cable is obvious since it's the only one of that size.
