My curser pad is not working and the curser is going crazy. I have tried all of the above but it still does not work

List "everything." That terminology is not helpful in trying to suggest a fix.

I don't know what other solutions you've tried but on mine it was like a "Ghost in the Machine" (moving around and clicking on things on its own) and all I did to fix it was to lightly dampen a cotton ball with window cleaner (evaporates) and clean firmly around the inside edge of the pad and to also click it firmly quickly and many times to clean out ANY kind of dust or debris that has fallen into the cracks. worked GREAT for me , so far!!???
