Hello everyone,

I have got a problem,
I set up my new computer today, I tried to power on it but nothing happened.
The fans start to spin but they stop immediately.
Here my setup

MB    Asrock X570 Phantom gaming x
CPU   AMD Ryzen 9 3900X
RAM   Apacer NOX RGB DDR4 3200 MHz 32 GB (2x16GB) CL16
SSD   Crucial 1TB MX500
SSD   Crucial 120GB BX500
PSU   EVGA SuperNOVA 750 G5, 80 Plus Gold

I don't understand, every cable is connected and all products are brand new.
One or more items are not compatible with the Mother Board?
Please help me I don't know what to do.

You can start by reseating everything .. 24pin and 8 pin power connectors .. try just 1 ram module .. reseat your video card (what are you using for a video card?) .. reseat your CPU ..

If still no go .. take everything out of the case and hook it up and see if it auto magically comes to life .. read the manual for your motherboard

Thank You ThreeDee,

reseat also the CPU? you mean remove the heatsink,CPU and put them back with new thermal paste?

I use an old AMD Radeon HD 7870 GHz Edition video card, but the phantom gaming x has a AMD Radeon Vega, I can use only this one.

I will try and talk to you soon

are you using a CONVERTOR on the graphics card to the monitor ?

like chaning dvi>vga or something

if so this may well be the problem

it needs to be vga to vga
or dvi to dvi

no adapters or convertors

You will only have "onboard" graphics if you have an APU installed .. the 3900x does not have integrated graphics .. you would have to install a 2200g, or 3400g ..etc .. something with integrated graphics to make use of the video outputs on the motherboard. You have to use a video card with your 3900x CPU

this is the problem

until you get a correct cable e.g.

dvi ti dvi
or hdmi to hdmi

you can either

connect the pc to a tv using a hdmi/hdmi cable

OR
use the lower pcie slot on motherboard

e.g. the x4/x8 one

Hello datonyb,
but the pc doesn't start even with no video signal cables linked.

Should be the RAM Apacer NOX RGB DDR4 3200 MHz not compatible with the motherboard?

Today I will try to remove the heatsink and the CPU to check all the pins...

have you tried either using the lower pcie slot or a tv and hdmi ?

please also note the first initial boot after building OR resetting bios
will take a few boot loops to let the bios assign ram training etc etc


we can only tell you things to check , we cant help if you dont try things exactly as advised and just reply telling us things didnt work when you had them set in a fashion they will not work anyway............

You are right datonyb, sorry about that.

I connected a cable HDMI / HDMI from the radeon hd 7870 to a TV,
unfortunately the card doesn't fit on the lower Pcie slot so I removed and moved the PSU but the card still doesn't fit because the hhd led, pwr btn, reset connection etc

I tried to connect the video card on slot close to the CPU and in the middle of the MB with the HDMI cable, I did about ten boot but nothing happened .
Sometimes fans spin 1 sec, sometimes 2 sec, no more than those

I tried these combination with 2 module of RAM (slot 1, slot 2)

Honestly, this sounds like a short somewhere on the board. Make sure you don't have the board resting on a metal standoff where it's not supposed to be, no loose screws stuck somewhere. Then maybe try another PSU. Then try powering on with nothing in the board but the CPU, not even memory. This should be enough for the board to keep the the fans spinning while getting stuck with a memory error code. Phantom Gaming X should have boot codes display to help with further troubleshooting.

When the boot takes two second , just before stopping the display code is 14.
What does it mean?

I just did, the motherboard is on a wooden table, clean, it doesn't power on

It's connected : 24 pin , atx12v1, atx12v2 , no video card, no RAM, no ssd.
it doesn't power on
I can see now error code 10 and stop.

I am really disappointed, I don't know what to do, this morning I removed the CPU and installed again . Please tell me what to try next. More than 1000 euro brand new components and the computer doesn't power on.

The codes are listed here https://www.asrock.com/support/faq.us.asp?id=334
They should also be in the board manual
10, 14 are problems with CPU or memory

If you have access to another CPU, try installing another CPU
The board also has BIOS Flashback - you can flash a new BIOS without anything plugged to the board but power and a USB stick. So you can try flashing the latest BIOS using this feature and see what happens.

I don't have another CPU AM4 socket and others ram to test.

I tried to update the BIOS using the manual, renaming (creative.rom) but the led button turns solid green, it means the bios is not operating properly.

What do you think, is it better open a RMA procedure for CPU and RAM ?
How can I be sure I don't have any problem with the mother board?

Make sure that you renamed the BIOS file you extracted from the archive, not the .zip archive you downloaded. Maybe you will need to enable displaying of file extensions to rename.
The function only works with specific USB port, make sure you plugged into the correct port.

As to what part to RMA, it's not possible to tell at this point whether it's CPU or the board. Maybe you could ask a local PC shop to test either your CPU, or your board for a few euros, if you currently have these kind of businesses open.
I don't think it's RAM because boards typically stay powered on with CPU fan spinning when RAM is not installed. If it's bad or incompatible RAM, the system can restart a few times, this is called memory training.

Yes I did, your info are the same of the manual, I tried the newest BIOS (2.80) and after the (2.70), still green solid led.
I don't know which BIOS version there was before because I have powered on the computer.

I finally updated the BIOS , version 2.80
Re-setup RAM and video card, I'm still working on the wooden table , power on ,
max it arrives till display code 15. I tried to change RAM slot but nothing new happened .

You will probably need to remove the CPU from the board anyway to have either replaced, so when you do that take a very close look at the socket, and the CPU pins, make sure there's no lint or thermal paste on them. Other than that, I guess you did everything reasonable in terms of troubleshooting, so you should replace the parts altogether, or one by one, whichever you prefer.

I tested the CPU with another motherboard and it doesn't work.
I am really disappointed, a new CPU Ryzen 9 3900X broken.
I tested also my motherboard with another CPU and it works.
Thank you guys
