Blackscreen issue on Lenovo LOQ: NVIDIA GPU not detected

To troubleshoot the issue of NVIDIA GPU not detected in Task Manager, Device Manager (hidden), and BIOS (GPU: n/a), follow these steps:

1. Check the NVIDIA Driver Version: First, ensure that you have the latest NVIDIA drivers installed. Open your web browser and visit the official NVIDIA website to download the latest driver for your GPU model.

2. Install the NVIDIA Driver: After downloading the driver, run the installer. During the installation process, the system will automatically detect your GPU and install the appropriate driver.

3. Restart Your Computer: Once the installation is complete, restart your computer for the changes to take effect.

4. Check Device Manager: After restarting, open Device Manager. If the NVIDIA GPU is still not detected, check the following:

   a. Expand the "Display adapters" category. If your GPU is listed but has a yellow exclamation mark, right-click on it and select "Update driver" > "Search automatically for updated driver software."

   b. If your GPU is not listed, click on "Action" > "Scan for hardware changes."

5. Check BIOS Settings: Enter the BIOS settings by restarting your computer and pressing the appropriate key (usually F2, F10, or DEL) during boot. In the BIOS settings, look for the "Graphics" or "Display" option and ensure that your GPU is set as the primary display adapter. Save the changes and exit BIOS.

6. Check Power Management Settings: Right-click on your desktop > "NVIDIA Control Panel" > "Manage 3D settings" > "Power Management." Set the "Preferred graphics processor" to "High-performance NVIDIA processor" and click "Apply."

7. Check NVIDIA Settings: Open the "NVIDIA Control Panel" again and navigate to "Manage 3D settings" > "Manage GPU utilization." Set the "Maximum GPU temperature" and "Power target" to "100%" and click "Apply."

8. Check System Settings: Open the Control Panel > "System and Security" > "System." Click on "Advanced system settings" on the left side. In the "Performance" tab, click on "Settings" under "Performance options." In the "Visual Effects" tab, select "Adjust for best performance" and click "Apply."

9. Check Windows Services: Open the Run dialog (Win + R) and type "services.msc" and press Enter. Scroll down to find "NVIDIA Display" and "NVIDIA NetworkService" services. Ensure they are set to "Automatic" and started.

10. Check Registry Editor: If all else fails, you may need to manually edit the registry. Open the Run dialog (Win + R) and type "regedit" and press Enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} and check if the UpperFilters and LowerFilters keys are empty. If not, delete them and restart your computer.

After following these steps, your NVIDIA GPU should be detected in Task Manager, Device Manager, and BIOS.
