PC Booting up for half a minute, shuts off, and resets process indefinitely

Recently I purchased an ASRock AB350M Pro4 motherboard along with an AMD Ryzen 1600x, and two new ddr4 memory sticks. After putting it all together, I was alarmed to find that my computer turns on for a moment (with no display, all lights and fans are running), turns off, and reboots, continuously until I manually shut off the computer.

After going through some tests I found a few interesting scenarios. The computer itself will run indefinitely, albeit no display, if the processor is locked in WITHOUT the CPU power pins in the motherboard. With the CPU power plugged in, the on-and-off process continues. This has led me to believe that the CPU is most likely the problem, although all the pins are straight and I have been very delicate with it. I do not have enough knowledge to pinpoint where the issue is, or why there is no display when everything but the CPU is powered. However I am hoping that someone here does have an answer or at least some suggestions.

My current build is:

Gigabyte GTX 1070
Ballistix 2x4gb RAM sticks
AMD Ryzen 1600x
ASRock AB350M Pro4
SeaSonic 520W 80+ Bronze Certified


Thank you very much.

Get a case speaker to you can hear the trouble code beeps. This will tell you which component is not passing the POST and then you know where to look for an issue. Case speakers are reusable in all of your builds. I have one in my gaming PC that is 13 years old now. and has been in 3 different builds. For $5 USD they are worth the time and cost.

You wont see an error code because your motherboard does not have the digital readout display on it for the code. While poking around be sure the Ram is seated properly in the slots. Try just one stick of ram, also if this does not work you can try a bench build where you build the PC outside of the case but a case speaker is easier and able to be gotten at any PC shop or Radio Shack if one is...

Do you get any beeps or see any error codes anywhere? Did you make sure EVERY cable is plugged in? Reason I ask is because there have been many of times where i forgot to plug one cable in and that was the issue.

Not seeing any error codes, and no beeps either (I don't have a mobo speaker so I wouldn't really know). After a few replies I definitely plan on just taking everything out and rebuilding, because it's worked for me before, but again, no error codes or beeps AFAIK.

Take it all apart and make sure you set plenty of time aside for this as you will want to take your time. It usually takes me about 9 hours to build a PC but thats because i'm probably "too" careful lol

So if my suspicions are correct and the speaker (which I plan to get tomorrow) points to the CPU as the problem, is it most likely just a dud?

I was thinking more along the lines the motherboard is the dud, but really only the speaker can tell you

Hey thanks for the help man, decided to fiddle around with some parts and it turns out that the RAM wasn't in the right slot. Out of all of the scenarios in my head that was not one of them. I did manage to pick up a mobo speaker for 3 dollars, I'm sure it'll be of great service in the future.
 
In the future if you have POST issues use your speaker. There will be short beeps followed by long beeps. count how many of each and jot them down on a piece of paper so you don't forget what they were, there can be more than one code. If you look in your motherboard manual you will find the trouble code cipher that explains what each code means so do not throw out your hard copy of the owners manual just in case. :)

I'm glad I was able to point you in a productive direction. Good luck with your system and as always have fun while doing so.
