View Full Version : Crosshair VIII Dark Hero - No POST QCode 90

03-08-2021, 03:23 AM
I went to wake my PC (not from sleep but just monitor off) and no response. I reboot using the reset switch, no video, no POST. Only Q-Code 90 and the VGA light on.

I tried:
1. Switching GPU with my other build
2. 1 RAM stick
3. No boot drive
4. Different Power supply
5. Different RAM
6. BIOS flashback
7. Moved my SSDs to my other identical build and it boots and works just fine

Am I stuck getting an RMA? Is the turnaround time that bad?

From what i've seen error code 90 resulted in RMA of the CPU ( and in some cases the board ). Sorry :(
