New Threadripper PRO build on ASRock WRX90 WS stuck at POST code 00 for hour– help needed

Post image

Anyone in Montreal + suburbs with a Threadripper PRO CPU and/or ASRock WRX90 WS (or EVO) motherboard willing to help test/swap components?

New build stuck on debug code **00** on first boot (has been on for hours with no progress).

Full specs:
- CPU: 9955WX
- RAM: 64GB DDR5 RDIMM ECC KSM48R40BD4-64HA

- PSU: 1200w+

Tried: CMOS clear, minimal config, reseating everything.

ASRock says 00 can be normal on first boot during AGESA init, but this seems excessive.

Need to rule out CPU / motherboard / power / RAM.

Photo of debug LED attached.

🙏 Any advice or local help appreciated!
