If this is only a recent happening, try system restore back to when it still worked fine.
I have a Dell Inspiron 15 3000 series and run Windows 10. I'm having difficulty with the pointer. As soon as you click on something,the pointer then freezes for several seconds,not allowing you to move it. Impossible to play games or do any work in a timely manner,as you have to wait for it to unfreeze each time you do something. Appreciate any help. Jenny
