Did it work previously and just stopped working recently? And, were you ever able to read some of the discs before but you can't read them now? If so, it sounds like your CD drive might be malfunctioning and/or the opticals may require cleaning. Also, that noise you are hearing is typical when a disc cannot be read (either because the player or the disc is malfunctioning).
