Try uninstalling NVIDIA drivers and DO NOT reboot, install 8.1 after nvidia driver uninstall. This has worked for some people
The Key to this is not to reboot. If you uninstall the graphics card and reboot the system windows will re-install the drivers automatically.
Steps
- Uninstall the card : Control Panel/ System / Device Manager / Video right click the video card Uninstall
- Go to the windows store and run the update.
