It might be that your GPU is malfunctioning and leading to Windows installation issues. If you're unable to install Windows with the dGPU connected, attempt it again after removing the 6800XT and using the integrated graphics.
It seems like you're checking if it's the 6800XT model. Just to confirm, remove that mention and let the PC run for a while using the integrated graphics. If it stays functional for a day or so without issues, it's likely a GPU problem. You can then skip the troubleshooting steps and go straight to the repair shop.
