Home this makes it easier...

I'll save you some pain...the YouTube thing appears to be an April Fools joke, so don't sweat that too much
The OS install should just give basic barely enough to run video and audio drivers, you need the Compaq factory drivers for the audio, and the Radeon drivers for the video. AGP or PCI? I ran a low end Radeon card for a while, and had issues getting the drivers to work at all...and the card would overheat when they did. go buy a better card. However, before then, look up "omega drivers", it's a freeware handbuilt driver set for the Radeon cards that seems to work better.

Do you have drivers from HP/Compaq themselves for the audio? Don't install the video drivers from Compaq, they'll conflict with the Radeon drivers, you'll need to remove them anyways.

Also, it's possible with a Wally World crappy computer (I have a crappy computer too ) that you have address conflicts.
