For some reason my computer will play dvd's but flat out refuses to run both audio and data cd's. Has this ever happened to anyone?

The problem started a few months ago but at that stage is was more of a temperamental thing, sometimes it would pick up on a cd, sometimes it wouldn't. I checked the drivers then and they were ok. I would like to check them again but i can't for the life of me remember how i got a look at them last time basically it's so bad now that when i put in a cd the computer claims there is nothing in the d drive at all. But if i put in a dvd it auto plays.

Suggestions? It's driving me crazy.
