I cannot get on my onboard audio/sound to work - what do I do now?
General trouble shooting instructions:
1) Make sure you have installed the correct audio drivers for your audio solution
2) make sure that your onboard audio is enabled in your BIOS The Basic Input/Output System is the program that microprocessors use to start computer systems. It manages data flow between the computers operating system and attached devices such as the hard disk, video card, keyboard, mouse, and printer. .
If, after doing both these things, the sound still does not work, reinstall your Operating System. If this does not work, contact your motherboard manufacturer for further support and/or have your PC checked by a technician

If you repair XP and it is an SP1 disc, it will remove SP2 as part of the process, though SP2 is unlikely to be the problem, you could download all the other updates in low numbers, go to add / remove to put a tick in show updates, note the additions which will be listed as hotfix / security update KB followed by a number, if you download anything from the update site which stops the sound working then you can remove it
