You could just have a shitty controller. When we got a Wii for my brother it wouldn't play any games and made a loud WHIZZZZZZZZZZZZZZ every time you tried to put one in, so it's not like the things are breakproof. The thing to do would be to take it to your local Gamestop or whatever and try the controller on theirs and see if it works better.
