First thing you have to do is give us some more information.
Is it a grinding, knocking or squeaking sound?
Have you any idea where the sound comes from?
When do you hear the sound?

many people describe the laser scanner spinning up as a jet-like sound. You could try replacing the scanner, but they all make some noise.
