One or more of your drive belts is probably broken. I had the same problem. You can get replacement parts or buy a tune-up kit for about $100, and replace a bunch of stuff while you have it apart. Be careful and attentive when taking apart, there are a lot of parts. But if you take your time and pay attention, it is pretty easy.
