Hi all,

I apologize for this long read but I wanted to be as detailed as possible in what I have and what I’ve already troubleshooted. I’m having a really frustrating time upgrading to a new build.

The components in question are:

Mobo: Gigabyte Aorus Elite Ax Z790 (ver 1.0)

Gpu: MSI GeForce RTX 4090 Liquid Suprim Ram: Corsair Vengeance RGB 64 GB

PSU: Corsair RMX1000x

CPU: intel i9-14900k LGA 1700

Case: Hyte Y70

OS: Windows 11

Special note:

1) hard drives are salvaged from a previous build as to not lose data. They are a 2TB SSD (not m.2 but will upgrade to that later) and two traditional disk hard drives, one at 10GB, another at 6GB. All connected and working fine

2) I bought Corsair’s premium 650w power cable to power the PSU as opposed to the kit that it comes with that requires four pcie cables to feed into one connector (looks ugly as f*** that way)

So far, everything works and it has booted, but the computer is not recognizing that there is a graphics card in. I reseated/took the GPU out and back in to make sure it wasn’t a physical issue. The graphics card lights up and the fans spin (which is a great sign).

When I go to device manager, it doesn’t even show as anything other than the MoBo for display adapters. Tried to download NVidia drivers both manually and through the “GeForce experience” but both instances error out saying it can’t detect nvidia hardware.

Going into bios, there’s an option under I/O ports and when I look, it shows nothing for being connected to pciex16 or the two additional pciex4 slots. One thing to note is that because of the case, I have to plug the card into a vertical port that then is connected to a gpu riser that plugs into the motherboard’s pciex16 slot.

Upon installing the OS and getting everything going, a thing called gigabyte control center installed and updated drivers to include the BIOS. This is where I think the issue is (could be wrong).

On Gigabyte’s site, there are bios updates that you can install and with the control center UI, a version called F4 installed as a generic update, but the version of this particular board matters as it is actually labeled ver 1.0 (on the gigabyte site, they have everything broken down into versions and OS) and that latest version is F10. So I try to do the manual install by utilizing a flash drive and the “Q-flash” option via booting into bios. I formatted the flash drive to fat32 (like YouTube instructions show) and install the unzipped file renaming it as “GIGABYTE.BIN” (also in YT instructions). When I try to install, it gives me “BIOS ID error” which basically means it’s not the right bios version despite checking the version on the physical board.

Here’s what I’ve tried so far:

Going to device manager and scanning for new hardware as well as show hidden items. Nothing pops up.

Uninstalling all instances of Nvidia drivers in old hard drive as I’m mentioned, it’s from an older build.

Taking out the CMOS battery for over 5 minutes to attempt to clear it. still shows version F4

Clicking and holding the “CMOS_CLR” for at least 5 seconds to clear the cmos/wipe bios version and it still shows version F4

Checked all physical connections, graphics card still lights up and fans still spin.

Any and all help will be appreciated, I’ve been troubleshooting for over 24 hours and trying to not have a full blown mental breakdown as the card was $2200 and I feel it works just fine.
