I have an HP Pavilion 17 running Windows 10 Home. When I'm on a website, sometimes the page will scroll to the bottom by itself. I have to press the delete key on the keyboard to stop the scrolling but it starts up again sometime later. The problem happens if the computer is restarted and it could take weeks before the computer stops scrolling by itself. I don't know what the issue is or how to fix it from the start.
