I am having problems with the mouse not working. Even using an wireless external mouse the mouse is opening all types of documents and web pages. As well as there is a permanent mouse on the screen.
I wonder if the touch pad is acting up. If you can, try to disable the touch pad and just use the mouse. If the mouse pad or board is going bad, it could have lots of phantom clicks as you see. You may be able to disable the built in mouse / touchpad using Windows Device Manager (if you can get there!) and just use an external only.
