PC won't boot properly from cold start

[golgarit]

Hey everyone,
I have a weird problem with my new build. I recently changed almost all of my old components and got myself:

Motherboard: Asus ROG Maximus Z790 Hero
Memory: Kingston Fury Dimm 32 GB DDR5-6000 Dual-Kit
Cooling: NZXT Kraken Elite WK
Graphics (from old system) : Gigabyte Nvidia 24 GB D6X RTX 3090 OC 24G

Power: Bequiet 850W straight power

HDD: WD Black SN 770 NVMe SSD and WD Black SN 750 NVMe SSD (from old system) ; both on an Asus Hyper M.2 Card on PCIe 4

Problem is, the system won't boot properly from a cold start and will always stop while loading Windows 10. You will see the "Republic of Gamers" logo and the running loading circle, but it won't go any further and the only option is to perform a reset. There is no error message or anything else, only the Q-Code will show 31 (memory installed).

Once you have done a reset you might run into the same problem again (had this 5-6 times before he got into Windows) or it'll load into Windows but on seemingly very low performance. The cursor stutters and it takes a good while to enter the PIN to get onto your Desktop. 

Once you perform a restart while Windows has been fully loaded there is no problem at all and the performance and temperatures are just fine. You can restart as many times you want and it'll always load the OS without a problem. Once you turn the computer off and leave it for several hours, you will go through the whole problem of "not booting" again.

I disabled fast boot in bios and also the fast boot option in windows. I also tried to disable the AI Tweak option in bios.

Any advice would be helpful.

The BIOS version is 1801. It happened, after installing a fresh Version of windows 10 on my new machine and switching from my old SATA to two M2.SATAs on the ASUS Hyper M2 card.

The memory (Kingston KF560C36BBEAK2-32) does not show up in the QVL, but is installed correctly. RAM slots and CPU are fine XMP is disabled.

Except for the booting problem, the system works absolutely fine.

Hello, @golgarit 

May I inquire whether the Hyper M.2 is installed in the PCIEX16(G4) slot and if the SSD is placed in the Hyper M.2_1 and Hyper M.2_2 slots?

We would also recommend trying to remove all SSDs and installing or cross-testing with a system disk individually to isolate any potential issues with the drives.

Thank you.

Hi,

the card is installed in G4. My understanding was that this is the only option to run the system with 2x M2. SSD. Both drives are placed in the Hyper M.2_1 and 2 slots.
Today it loaded into windows directly and without any resets. No changes where made.

I recently changed the OS to Win11, and the problem was still there. With the latest update the problem seems to be fixed. Four cold boots without any problem. 

Still don't know what caused the problem though.
