My first PC had the Voodoo 3 3500 TV AGP. It was a kickass card when I got it in February of 2000. Shortly thereafter, Voodoo sold out to Nvidia and all driver support was dropped. It was fortunate that a Windows 2000 driver was available, or the card wouldn't have even worked in Windows XP which came out like a year and a half later. I got rid of that card like 6 or 7 years ago.
AGP (the slot your card goes in) is an obsolete technology, so you probably need to get a completely new computer. Your motherboard probably doesn't support SATA hard drives or even USB 2.0. It's way past time to get a new computer.
