num key 3/pgdn key behaving erratically in windows 10

after upgrading to windows10, I find my laptop behaving awkwardly of late . The pointer starts moving down without any pressing of key . I found out that it is due to the misbehaving of numeric key 3/pgdn . I took out the key and cleaned , but still it
behaves same way. I suspect this due to some bug in windows 10.

Further the mouse pointer disappears now and then. This never used to happen in windows 8.1.

It would be very helpful if any solution is suggested !
