The Mirage
Driver did not come with this PC. You may want to wait for your Dad, but I think I would make a
System Restore Point - Create then Disable or uninstall the Mirage Driver from Device Manager and see if it works then, if not then you can use system restore if need.
If you can list what is installed on this PC I can look if anything uses Mirage
Drivers, go to Control Panel Programs and Features and make screenshots or a list.
