Double check the speaker connection and make sure you are in the correct socket at rear of comp. Check all the wiring inside the case to make sure you didn't knock anything loose when cleaning. Go to Device Manager and look for an exclamation point, etc next to your audio device or any other component. Not familiar with that mobo, but wonder if it is proprietary for HP. Uninstall the onboard audio in device manager, reboot the computer, and let Windows redetect and install it if XP has the drivers. Check your HP CD's that came with the computer also for the audio drivers.

I have a different mobo, but I lost onboard sound occasionally too. Think I have it licked, but hasn't been enough time passed yet to be sure. ANyway...

What Intel told me to do (it's an Intel board in a new build), after I'd exhausted other possibilities, was to clear the BIOS and do a BIOS recovery. They said a damaged BIOS could cause the onboard sound to disappear. HP will probably have a different method than Intel of doing this, so check your manual, but the principle is probably the same. If you do go this route, just make sure you go into your BIOS and write down all your custom settings.

I'm bringing this up as a possibility, because you said this happened after "took it apart to clean it". If static electricity got to the BIOS while you were cleaning, it could be damaged. Try helpmeout's suggestions first--if they don't work, you might consider this.
