New Member AMD Motherboard Thread

My ASrock B850M Pro-A with Ryzen 5 7600X suddenly started to reboot after shutting down by the OS. I am running Manjaro Linux, latest.

First I tried to power down the system by "sudo poweroff" or by "sudo shutdown -h now" instead of the GUI button. But it kept rebooting.

Then I watched precisely, at what stage the computer would turn on again and I found out, that the OS is already finished, the fans and the harddisk start to spin down and then the restart happens.

I have checked all BIOS items, which could wake up the computer like PCI or LAN etc. but I did not find any setting, which would cause the reboot.

Searching the web, I found the hint, that sometimes a PSU could be the cause. But my PSU is a 350 W bequiet! PSU which formerly was used in my older computer, having a total operating time of about 500 hours only. The PSU was never causing any problems.

How can I find out the reason for auto-rebooting after shut down?

Hey pp-tol, your new thread can be found here

found it:
go to
Avanced/AMD CBS/NBIO Common Options/GFX Configuration

set line
dGPU Only Mode to "enabled"

then integrated graphics is deactivated.

Hello everyone! I just submitted a support ticket with ASRock and figured I would share here as well in case anyone else is having issues.

Setup:
AMD 9950x3d
XFX 7900 GFX
2 m.2 SSDs
128GB of CMP64GX5M2B6000Z30 RAM (4 sticks total)

When I built the system, everything was working just fine and here recently I started having this boot issue. I press the power button, I'd get double 00s on the MOBO which doesn't appear to be in the boards manual, though through Google, seems to relate to a CPU issue.

I have tried updating the BIOS to different versions (Currently trying to flash back to 3.20), cleared the CMOS multiple times, pulled the CPU to check for bent pins or burns/discoloration (there is none), checked all my wiring and cables, everything is seated.

The weird thing is sometimes after a while (i guess when it feels like it), it will actually boot and stay running until I have to restart or shutdown, then the problem comes back.

Has asrock thought about a on board programmable microcontroller for people who want an opensorce approach of controlling ARGB through OPENRGB?
