System won`t boot ... after display Asrock logo, I see only one " - " in upper left corner
OS tested : Ethos and HiveOS
Boot : from USB ( i also try to boot from SSD )
VGA : Onbord ( and with 1 or 12 gpus, same problem )
The MB is connected with 2 molex + 1 sata from the same PSU
I made test with same USB in other rig and works fine, also all GPU`s/risers works without problems ... so problem is from MB. One hour tested diffrent BIOS settings without success ...
Thanks and I`m waiting some advices
Remove gpus, go into bios, disable CSM.
On my board with AMD gpus, CSM always gets reenabled if the rig hangs/freezes
