Microsoft Windows 11

I am currently using a laptop with the Advanced Optimus performance feature. However, when I check the option to use only the GPU in the Nvidia control panel, the screen freezes or the system crashes, and it automatically switches back to Optimus. When I set the BIOS to Discrete and boot, I encounter a black screen, though I can hear the Windows boot sound and the fans are functioning normally. In an attempt to resolve this, I had the motherboard replaced twice while I was in Korea, but even after the repair, I can use the GPU ONLY option for just one day, and the same issue reoccurs the next day. Additionally, when I completely uninstall the graphics card using DDU and reinstall it, I can check the GPU ONLY option for just one day, and again, the issue reappears the following day. No one has been able to provide a clear answer to this problem. Even HP has only repeated the same thing without offering a solution. I’ve run a full diagnostic check using HP's diagnostic system, and no hardware issues were found. Please, I need your help.
