System incredibly slow even on bios and a lot of other things

Hello everyone, I don’t know if anyone here can help me, but I’ll try to explain things as clearly as possible.

I recently bought a new high-end setup:
Hyte Y70 case
ASUS ROG Strix X870E-E motherboard
AMD Ryzen 9 9900X3D
ASUS ROG Strix 5070 Ti
ASUS ROG Strix 1000W Platinum Edition PSU
ASUS Ryuo IV water cooling
Crucial P3 Gen4 1TB SSD (from my old PC, formatted and converted to GPT)

First of all, the riser cable is Gen 4 and most likely dead because I get a white LED on the motherboard (VGA not detected) with two different GPUs tested. Also, it’s impossible to mount the GPU horizontally because apparently the case wasn’t designed for that — honestly if I had known, I might not have bought it. So I’ll probably need to buy a new riser cable or maybe even a new case.

Besides that issue, after the first boot we updated the BIOS to the latest non-beta version. Then we tried — or rather struggled — to install Windows 11. We tested a first USB stick in USB 3.0, but the loading times were endless and we never got past the first stage. Then with a second USB stick (both previously formatted in FAT32), it “worked,” but there were 40 minutes to 1h30 between each step until the Windows download stage.

The download completed, the PC restarted, and then we got this message:
“If you want to upgrade Windows, remove the USB and select Yes. If you want a clean install, select No.”

Basically, an infinite loop:
choosing the first option sends us straight back to the BIOS, even after several restarts, choosing the second option restarts the installation from scratch.

The BIOS has been extremely slow during all troubleshooting. In the end, we couldn’t boot Windows at all, so we took the NVMe drive to a friend who formatted it on his PC and installed Windows on it without any speed issues. Then we put it back into my PC, and surprisingly it worked (even though I know that’s not recommended).

But now everything is insanely slow: boot times, BIOS navigation, every single Windows action.

  1. We obviously tried changing the NVMe slot multiple times during the process (yeah, we’ve been working on this for 72 hours now).
  2. After that, we started investigating where the slowdown could come from. Using a benchmark tool, we noticed the CPU seems heavily undervolted/underclocked: core speed never goes above 600 MHz, core voltage stays around 0.600V. (I attached a screenshot.) We think the issue could come either from the motherboard, BIOS settings, or BIOS itself, but honestly at this point I have no idea anymore. A professional opinion or any constructive idea would really help us at least identify where the problem is coming from, because my brain is completely fried and my friends’ too XD. Thanks to anyone who might have an idea.
