I recently bought a 3rd party N64 controller from eBay.com and when I went to use it I noticed something was wrong. The first game I played was 007: The World Is Not Enough. On the very first level my character (James Bond) started moving by himself. I also noticed that when I flicked or barely moved the stick a little that it would also start moving on it's own the way I flicked it. The controller has not been damaged in any so far. What should I do?
