After PC construction, I stay on AMI American Megatrends.

Hello, I have built a new PC, and although it is not the first time I have built PCs in my life, it is the first time I cannot go to the Bios.

I see the information of the components detected, and I see a message which tells me to go to bios or ignore in F1.
But, any button on the keyboard that is detected and working (because it lights up showing it is connected to the motherboard) does not work to take me to Bios or boot normally.
I haven't installed Windows yet because I can't do it either since I'm stuck on this screen, however I put a SATA disk back into SSD which had been used in Windows 11 on an old machine, but that I don't plan to install the new Windows on it but rather on the M2.

I show you in pictures what I see on the screen remaining stuck on it.

My question, why did I get there? I don't understand, although I checked the connections, it's not complicated for me, everything is good.

On the other hand, I did a bios update flash after finishing assembling the PC. I took from the official Asus website, to my motherboard. I turned on the key, the user manual says that if it flashes 5 times and then stays on, there is an error with the key. But this was not the case, it worked correctly, it only flashed until the end before turning off. I left the flash pressed for 3 seconds with the light flashing 3 times initially, as indicated in the instructions for use of the bios flash.
Did I do something serious in flash bios so I can't enter the bios remaining on this screen ?

There is, however, a Bios inside since on the screen at the start of component detection it says ACPI bios revision 1501.
Which corresponds to the latest Bios update taken here:
ROG MAXIMUS Z790 HERO | Gaming Motherboards｜ROG CH (asus.com)

There is also error code 98 on the motherboard with yellow green light which matches according to the manual for color; problem at boot.
Normally the color should be darker green to indicate normal, if I'm not mistaken see photo.

And code 98 on the manual corresponds to saying:
The console input peripherals connect.
That doesn't mean anything to me, I don't understand.

On the other hand, the RAMs are off and the lights are off, I think it's normal if I haven't configured anything on the motherboard with Armory.
On the other hand, the screen says RAM at 3600, when in reality I bought a frequency of 6600 Hz.

Is this problem caused by this lack of connections on the 24 pins, 1 has no metal connection (empty)?
On the old motherboard there was no problem with this connection, so I tell myself that it's normal.

I redid the bios flash since removing the battery brought me back to the AMI screen without being able to go to the bios.
I come back to the Asus screen after the flash, also pressing F5 to reset. Then pressing F2 it doesn't want to enter the bios it puts me back on a black and lit screen waiting for what's next.
I had the idea this time plug in the Windows installation key and I come across error 32 and 33 on the motherboard Q-Code which corresponds to searching the memory, not launching the Windows installation key.

It's quite blizzard, there he tells me it's a problem with the RAM memory however SWQL corresponding to the Gen 13 and 14 processors, (not the 12th generation according to the characteristics on Asus). If I do not put the installation key it will remain in error indicating hibernation status and lit black screen. And, if I remove the battery and put it back after 10 minutes I return to the AMI screen.

However there is no red, YELLOW or WHITE LED error indicating either CPU, graphics card or RAM.

The screen does not turn on via HDMI on the graphics card integrated into the motherboard, yet with an I5 13600K CPU I can use the motherboard's graphics card.
So, only my 3060Ti works, but only in display port, HDMI is not recognized, perhaps to be adjusted after driver installation.
In the meantime I can neither go to Bios nor install Windows and freezes on the AMI screen if I remove the battery for 10 minutes. The bios flash updates and resets the screen to Asus with F2 written to go to the bios, but after that nothing is left.

My rams are
CMH64GX5M4B6600C32
So compatible for 13th and 14th generation CPU, (not 12th generation according to the search on the Asus site for my motherboard).

Good morning,

I managed to get into the BIOS, it was to finish unplugging the SATA of HDD hard Disc. Yet this Seagate brand HDD The serial number is recognized in the compatibility of the motherboard, having searching the SWQL list of various external support.
So by unplugging I was able to get into the bios, but the disc SSD also I had to remove it because the PC did not want to enter the bisos either after detachment from the HDD. On the contrary, it launched the old windows installed in the old machine, although it left in black screen I also had to detach it from its SATA cable.
So understanding is that the HDD prevented the SSD in the Windows, and the SSD prevented in the same way as the HDD from entering the BIOS.
It is a problem that is really unknown to me in logic. Finally maybe I will see better why after and I will be able to solve this problem in the BIOS. But, no it's the Bios disaster.
The keyboard responds to come in F2 in the BIOS, but afterwards it does not answer in the BIOS and or for the Windows installation which I can not put my Windows key. And, therefore in the BIOS I can not pay the time which is more than 12 hours of difference and nor the date which is late for 2 days.
The BIOS captures that I have an M2 installed, but it is in raid and an absent volume the outstanding I want to install Windows, (which automatically also absent in the start -up in the BIOS).
It is an M2 chosen from the list of series compatible in research at the Asus site.

There is a positive thing is the mouse that works wherever I am, however a very poor mouse without known brand.
The keyboard is a logitech sector and at the same time Bluetooth if I wish, I know it works it has responded in F2 to enter the BIOS and lights up the recharge when it connects.
I tried it to connect it to the interface, the problem does not solve. Although I do not understand why I have a USB that does not work in an interface, if his pale brother works and who are linked to the same cable to the connection in the motherboard. But, this is not an important problem, the other 3 on the interface works is sufficient.

I encounter other bios problems, as certain parameter that I do not find according to the instructions for use which does not explain everything, and the bing IA is well complementary to understand things but does not know how to direct the problems one by one.
As for example, I don't understand why I don't have XMP2, while the old mother cards 10 years ago there are XMP and XMP2.
I do not know why either he refuses to operate my RAM in 6600 MHz, the bridle at 4800 and sometimes 5100. Nor the Overclocking IA can help me who is generally automatic by itself, because it also poses a stability problem.
Certain options in the BIOS which are grayed instead accessible.

Anyway essential there is to be able to recreate this volume not detected in the motherboard, although it detects my disc M2. I know that there is a manipulation to be made as a guest of order via by the possibility of the USB key install Windows, I just see?
But, how can we do if the keyboard does not respond in bios and wanting to put the Windows key?

Hello, @dubignyp 

From the BIOS image you shared, may I ask if you tried clearing the CMOS and checking if the problem persists under the default BIOS settings after the update?
As indicated in the last section of the user manual, the appearance of Q-CODE 98 suggests a console input device connection issue.

This could imply potential problems such as incorrect hardware connections, device malfunctions, or driver abnormalities, just as the yellow-green Q-LED indicator light further suggests a possible booting anomaly.
In light of this situation, we recommend referring to the troubleshooting guide on the "Motherboard - No Power/No Boot/No Display" , specifically the section on "Test with minimal components, isolating the possible cause."
If necessary, you may consider cross-testing with a different keyboard.

Regarding the memory, may I inquire if the part number of your memory is CMH64GX5M4B6600C32(Ver. 5.43.01)?
We recommend starting by installing a single memory module in the recommended DIMM_A2 slot and booting under the default BIOS settings to ensure that the system POST correctly and enters the BIOS and OS before gradually adding two and then four memory modules, verifying stability step by step.

Thank you.

It was really the compatibility problem of HDD Seagate 6G serial ST1000DX002 number accepted from QVL list in asus.com, and compatibility problem of Lenovo SSD.
Luckily I also had an M2 threaded into the motherboard.

Everything returned to normal once I went to the bios and activated the SSD and HDD, then my HDD and SSD disks were no longer missing, they no longer prevented me from going into the bios.

The keyboard simply had to unplug and reconnect its Bluetooth USB key, I didn't understand this problem why it was deactivating, but now it no longer does.

I opened another topic about the problem with the graphics card integrated into the motherboard which is completely missing, impossible to install the Intel driver, no presence in the peripheral manager and no screen on after building the PC. Requiring to use the external graphics card in PCIe, yet everything is by default the bios, everything is activated for the internal graphics card.

I bought these RAMs:
