Unable To Play CDs

[#1]

I tried to download one of my CDs onto I Tunes and I am unable to do this when I put the disc into the drive there is a rotation sound for some seconds but no recordings show on I Tunes,I have tried a DVD but the same thing happens I have not played a cd for sometime.If I did a system restore would that help.

Is the CD player showing in my computer ? as a drive letter .
if yes can you use windows explorer to see what files are on the CD , or try another CD to see if it runs ok
