RTX 3050 Ti Mobile Won’t Install Drivers on Prebuilt STGAubron Desktop (Windows 10)

Hey everyone, I’m stuck and don’t know what else to do. I have a prebuilt STGAubron gaming desktop with:

• Intel Core i7 (up to 3.9 GHz)
• RTX 3050 Ti Mobile GPU
• 16 GB RAM
• Windows 11 Home 64-bit

The problem:

• GeForce Experience sees my GPU but says: “Cannot detect compatible hardware / this version of Windows is not supported.”
• I’ve tried:
  • Clean installs with an uninstaller that NVIDIA Support sent me
  • Manual driver downloads from NVIDIA’s website
  • OEM drivers from STGAubron (no response from them)
  • Reinstalling GeForce Experience

Nothing works. Previously, a support agent sent me a file that installed the drivers successfully, but I no longer have it.

System info that may matter:

• TPM cannot be found
• Secure Boot status unknown
• BIOS Mode / partition scheme unknown
• Fans spin and LEDs are on, but during System Restore the “initializing” screen just spins

I’m basically stuck now with what I assume is the Microsoft Basic Display Adapter. I am currently trying to get it to revert to a restore point I had before running the uninstaller but have been stuck at "System Restore is restoring the registry...".

I have tried all I can think of, so now I turn to you.
