hmm thats strange..2 years isnt long, optical, and yeah i have an optical and mines about even 3 years...
If you say its had heavvy use then maybe a part is lose or something, not sure..?
But then again it might pay off geting a new one if you have the spare cash to spend and you still cant find out whats wrong, like alot of mucking around..
