Question ROG Crosshair VII not posting.

Mar 24, 2019
Hi all,

First the specs;
  • Corsair RM1000x
  • AMD Ryzen 2700x
  • AMD Radeon VII
  • 32gb Corsair Dominator 3000mhz CL15
  • 1TB Samsung 970 EVO
  • Asus ROG crosshair hero VII
  • Cooler Master SL600m
So I've been running into a no post issue;
  • no qcode
  • no indication LEDs
  • no fans
  • only "CPU not ready" LED when on EATX 4 pin (doesn't do anything on 8 pin or 8+4 pin, standard on 8 pin)
  • only RGB leds on MB works, Start button lights up
  • BIOS update seems to work
Here is what I've tried so far;
  • reseating CPU and cooler
  • 8 pin or 8+4 pin CPU
  • cleaning CPU
  • clean CPU sides for excess thermal paste
  • clean pins
  • clean MB socket
  • loosen MB tension
  • loosen cooler tension
  • every RAM combination and socket, including only one dimm
  • PSU out of case to exclude PSU case-short
  • clear CMOS and BIOS update
  • MOBO, RAM, CPU, NVME only
  • change NVME SSD slot
  • reset + start in quick succession
And probably some other combinations. For the life of me I can't get this thing to post or do anything. Haven't gotten even the indicator LEDs.

My question is; something has to be bricked right?

I can't imagine anything else at this point. Any tips?

Sorry in advance if this is the wrong forum, first time building and first time has gone horribly wrong so I'm getting desperate.

I have the same motherboard, CPU, and GPU. They perform quite well.

Do you have an alternate GPU to use instead of the Radeon VII, just for troubleshooting? By the way, you must have a GPU installed for the system to boot.
Thanks for the suggestion, don't have one lying around but I can get my hands one one.

Quick question, is it normal for the cooler to clamp down extremely tight?
