So the rear cassette on your wheel?

It sounds like it is dirty and just needs some cleaning. You could need some adjustments also, have you taken it back in since you bought it for adjustments?
Take it in to your LBS and just have a one over, let them know- it might just need a basic tuneup or just a simple cleaning!
