Can't Play Anything Anymore

[AngelzStylez]

Ok, heres the problem:

The dc loads up to the the dreamcast screen and goes to the options screen with play game, settings, music, and vmu setup but -

1) My dc cant read any of the games ive burnt anymore (they used to work so well)
2) I even tried a music cd, and it wont play that either

Is my dc fried? i really dont wanna get a new one, any ideas anbody?
Please email me if u have a worthwhile suggestion, any help is appreciated.
