Burning does not work anymore?

I have a laptop with included CD and DVD tray, and so far I could always wonderful DVDs & CDs play or burn. But now, suddenly I can't burn CDs anymore. Burning DVDs and watching works perfectly. CDBurnerXP shows burning process could not continue (although he did not even start), because no burner was detected. Install a burner and restart CDBurnerXP to write to media. The other burners just testify to failure or failure to burn. What shoud that? Should I immediately become a specialist or you know another Metode.Schon thank you, private756

Replace drive. DVD burners cost about 10 euro and is good.
