after installing xp again i now have problems with my registry and need to clean it. 
Hi and welcome to TSF
If the installation was working ok but has been corrupted, you could try a system restore (right click My Computer>Properties>System Restore tab)
Have you installed the mainboard drivers? Your soundcard drivers may be on the same disc.
If the windows installation is a bad one, I would suggest downloading the drive manufacturer's free diagnostic software from their website (usually goes on a floppy but can be used on CD) and zero the drive - Low Level Format - and start again with the windows installation.
You can use Belarc to determine the make of your drive:-
