I have had the same problem with my scanner and the annoying clicking sound a few months ago. My dad called up his friend and he came and fixed it up for us (don't know what the hell he did). This same guy cleaned my computer free of viruses and spyware and gave me a new OS (xp) for free. Man that guy knows soo much about computers. Anyways, you might want to call a technician OR like others have suggested gather your pennies for a new one.
