computer does not recognize audio or blank cd's

[NooNoo]

Welcome to Windrivers lottamiata

What music player do you use when you put in a music cd?

On the blanks, have you tried a different brand of blank? What are you using to burn a cd?

Oh and do you mean that you don't always get the "autoplay" asking you what to do with music and blanks?

Does the computer boot from a stamped CD? That's the easy test before trying to mess with the registry.
If it doesn't then try cleaning it. If it still doesn't boot it's about to die.
