Hi! I'm John.
I understand your concern. I'm here to help you with this. The fact that you can see the GPU in BIOS but not in Device Manager suggests a hardware issue with the graphics card itself, rather than the motherboard or other components.
What troubleshooting steps have you already tried?
In the meantime, here are a few things you can check:
> Reinstall GPU drivers: Uninstall and reinstall the latest drivers for your RTX 3070 from the NVIDIA website.
> Or, completely uninstall all NVIDIA drivers using Display Driver Uninstaller (DDU) in safe mode. > Download and install the latest drivers directly from the NVIDIA website.
> Check BIOS settings: Make sure the BIOS is set to use the dedicated GPU instead of the integrated graphics.
> If your ASUS TUF15 has ASUS Armoury Crate software, check the GPU mode settings. Sometimes, switching between iGPU mode and dedicated GPU mode can resolve detection issues.
> Test in another PC: If possible, install the GPU in a different computer to confirm whether the issue is with the GPU itself.
Let me know what you've already tried and how it goes, and we can go from there!
