AB350 Pro4/Ryzen 5 1600 No Post

Hello,

Parts:
CPU: AMD Ryzen 5 1600
Mobo: ASRock AB350 Pro4
RAM: 2x8gb  GeIL Potenza GPR416GB3000C15ADC not found in QVL list

GPU: EVGA GTX 460
PSU: EVGA SuperNOVA 650 G1 120-G1-0650-XR 80+ Gold 650W
 
Problem:
The computer does not post. The CPU fan spins, the GPU fan turns but then nothing, spins for about 30 seconds, shuts down, and re-starts. No posting. I do not have anything else hooked up. The MB is on the table with only GPU, monitor, and power supply connected. I start the power by shorting pwrbnt to gnd. Both CPU and GPU fan starts but nothing on the monitor. After about 30 seconds, everything shuts down, and then re-starts.

I tried RAM in the A2 & B2 slots, A1 & B1, A1 only, and B1 only.
I do not know what the Bios came with it, there is no sticker I can find.

 
I have checked and re-checked all components, disconnected and reconnected, re-seated RAM, checked the 24 pin connection, checked ATX12 connection, also checked the GPU connection. I also tried GPU in PCIE2 and then PCIE4 slots.

Before I purchased this board, I tried Gigabyte GA-AB350-gaming 3 board. That board did not post either, so I sent it back and replaced it with ASRock board. Now I am thinking, the Gigabyte board was probably OK but the problem could be with memory, power supply, or CPU. The graphic card I pulled from my working computer so I am thinking that may be OK. I do not have any extra power supply, memory, or CPU to narrow down the issue.

 

What is next component I should order or should I just give up on this?

1) memory, 2) CPU, or 3) power supply.

I am thinking memory is most likely candidate, which one 2x8 will you suggest?

Been struggling on this for about 3 weeks now. I have assembled 3-4 computers years ago but never ran into frustration like this incident.

 
Thanks in advance.

Seems you did not remove the battery?

smithrock, you probably need to buy a speaker to hear the beeps - certainly worth the effort.  Something like this - https://www.newegg.com/Product/Product.aspx?Item=N82E16812201032&cm_re=mb_speaker-_-12-201-032-_-Product  But hopefully you can get one locally.  I am curious what you mean by ATX12connection.  The CPU has a 24-pin connector, plus an 8-pin and perhaps a 4-pin.  Make sure all are plugged and oriented correctly.  We have seen more that one user rotate the 4-pin 90 degrees.  If you have or can borrow a voltmeter I would suggest checking voltages.  Since your system powers up check the 24-pin, 8-pin and 4-pin.  Also check the power to the GPU.  12 volts is getting to some parts, but perhaps not others.  Hopefully the beeps will give you a good hint - please let us hear.  Enjoy, John.

Sorry, I meant MB 24-pin connectors and 8-pin CPU. I checked all connectors again. Right now I do not have access to speaker or multimeter.

-Cleared CMOS. disconnected the power, shorted bios jumper, removed battery, waited 15 minutes, put back jumper at original, placed the battery back
-Found one spare power supply, Cooler Master 550. Swapped the power supply, re-checked all connectors.
-Swapped GTX 460 GPU with GPU from my working computer (EVGA geforce 8800 GT) and re-connected 6-pin power on it. The GTX works on my main so I know it is OK.
-Removed CPU cooler, removed CPU, put back gently and make sure it was re-seated, put back the CPU cooler.

still no post, exact same behavior, turns the cooler fan, turns the GPU fan, nothing on monitor, after 30 seconds everything shuts down and restarts.

GPU is OK.  I eliminated power supply issue by swapping with another one. (two bad ones unlikely). Now, I am down to Memory, MB, or CPU. This board is my second board. Gigabyte board did not work either). So issue with MB could be eliminated.
Is it Memory or CPU? what you guys think?
You all are awesome. Last weekend, I was pulling my hair with Gigabyte MB, posted questions in that forum and no one really helped me. GeIL memory I bought because it was on Gigabyte QVL list. It is not on ASRock QVL list though.

sorry for the long post and thanks in advance
 
 

I am sending RAM back.
Do you think I should try to RMA the MB as well? Should I get the same MOBO or try different and more expensive one?  Ironically, both Gigabyte and ASRock mobos I tried from newegg had mail-in rebates. I wonder if those with mail-in rebates are from some bad batches or older bios giving me some griefs. My usage is typical and not intending to do any gaming or overclocking.
What about CPU? what are the chances that I have bad CPU?
