It sounds like what you've done was reformat your system, rather than reboot. Is that right?
What you are actually missing is not the cards but the drivers to make them operable. I'm not real familiar with 2000, but
here's an excellent tutorial for updating drivers that will help guide you through the process.
Here's a link to the HP page that has all the original drivers for your windows 2000 system, and
here's another link to the xp drivers. You should probably choose one OS or the other, rather than trying to install 2 of them. Your system will run better for it...You can download them from antother internet connected computer and burn the download to a cd if you have'nt internet access from your system at the moment.
Here are a couple of links that may be helpful from your hp support sites, here ,

You might save yourself a lot of time updating windows if you consult articles
