When a Mouse is More Then a Mouse

Yesterday my computers mouse decided it had a mind of its own and no matter how much I tried to go here it would go to three other places.  Some places I have never seen on my computer before.  I tried everything.  Scanned for bad files. Removed extra storage.  Defragmented the disk you name it I tried it.

Finally I slightly pounded on the mouse and well here it is working.  Was something stuff under the mouse that held the pointer  prisoner?  Did I set if free by knocking it lose.  I am not really sure but when a mouse is more then a mouse nothing gets done on the computer anyway.
