Zenith II Extreme Alpha HDD Code 02, CMOS Error

[dj.idol.89]

Hey everyone, I’m having an issue with my pc boot right now. The last few days whenever I start my PC for the first time in the morning after shut down the previous evening it throws the following error: “Reboot and select Proper Boot device”.

If I manually shut down and turn back on it would boot fine, however I tried looking into the error because it was annoying to have to start the PC twice each morning. I saw people saying disabling “CMS” in BIOS fixed the issue so I did that and now I’m getting post error and cannot get to BIOS. I’ve tried clearing CMOS and now get the following error on the motherboard screen: “HDD Code: 02” then “CMOS Error”

Hi,

I had same problem, on a Zenith Extreme II, worked fine and suddenly i got HDD 02 showing for a bit and then POST ERROR. Sent the MB for repair.. meanwhile i got tired of waiting and then got the Zenith Extreme II ALPHA. Same error on first boot!

Asus Zenith Extreme II Alpha
AMD TR 3970X
128 GB ram 8 modulles of 16GB (G-Skill AMD memory)
ASUS RTX 3090
PCIe gen4 WD-black 1TB

I suspect that the 3090 might be the issue.
The MB gets passed the Yellow and the Red leds test and is stuck with the White and the Yellow/greenish LED lit up indicating VGA and post issues.

I did try to use another GPU RX580 in my none-Alpha version no luck after the pst error occured.

ASUS please assist!
