Hello,
I did two exact same builds with this mobo and they worked for 10 months like a charm.
One of them, all of the sudden, during casual YT session the screen froze and got BSOD. Since then the system is unable to boot, no POST, no video. The mobo leds are going in endless loop.
Video of the issue: https://www.youtube.com/watch?v=9lPmjGanSNc" rel="nofollow - https://www.youtube.com/watch?v=9lPmjGanSNc
Both system spec:
ASROCK B650 PRO RS
AMD Ryzen 5 7600X
Kingston FURY 32GB KIT DDR5 5200MHz CL36 Beast Black RGB EXPO
ASROCK Radeon RX 7800 XT Steel Legend 16G OC
Samsung 980 1 TB
Corsair RM850 White (2021)
NZXT KRAKEN 240 RGB Matte White
NZXT H5 Elite White
Bios ver:1.28
Troubleshooting done:
- standard DRAM module shuffle/swap
- video cable move to mobo
- remove CMOS battery
- short circuit CLRCMOS1 (30sec)
- flashback to BIOS 3.01
- flashback to BIOS 1.11
Can anyone point me to what HW component could be the issue with please ?
Is there a page/kb/article that discuss and explain the meaning of the mobo led blinks please ?
Any help is much appreciated.
Thank you.

If the board doesn't post, it looks to me most like CPU or RAM. I can't see any code in the led, it looks like constanting glowing to me. But there seem to be small letters underneath it. And if I look really hard, it looks like first CPU and DRAM glow simultaneously, then it skips over VGA to rest on the fourth one, which I can't read. Maybe there is your answer.
You can of course find the manuel on the product page by googling the board, but you've probably tried the manual.
There is no official supoport here, if you look around. I'm just an amateur, without an Asrock board (potential buyer), hanging around.

(I should have removed at least the second sentence, but one can't do that afterwards.)
