(Lack of) Sound problem

I am using WinXP Home. Sound on startup and playing music(CD and DVD drives,Musicmatch and Mediaplayer) all worked satisfactorily. I loaded Su Doku from PC Advisor CD (Oct 05) a few days ago - apparently successfully.
However, the startup sound for windows and game completed sound now doesn't play although it did at first(MM + Mediaplayer still work). Sounds and Audio Devices in Control Panel say my problem is DpvSetup.exe. When I looked for that in Google the solution recommended talked about microphones but I don't have one. Any suggestions/solutions?
