Well, that is definitely a problem.
Power the system down and physically remove the 1060. Reconnect your display to the integrated video you were previously using.
Power on and let Windows detect the "new" hardware and re-install the video drivers.
Once fully installed, power the system down. Re-install the 1060 and connect your display to it. Restart the system, does Windows detect the now "new" video device and does it attempt to load drivers?
