this is known as hanging when the pc gets stuck on a particular screen like this

i can't remember exactly how to sort it so this will act as a bump

Other than remarks about letting sisters near computers.....
This is happening at about the point windows is loading drivers.
Restart in safe mode and remove the device I think you have just installed.
