|"how do i find and install drivers for it"|
You should have done that before you reinstalled XP. We have no idea which video card you have (apparently, neither do you) so you're going to have to somehow come up with your complete system specs. Any drivers on the XP disc are 10 yrs old so you are going to have to find updated drivers for the motherboard chipset, video, sound, network, etc. Since you didn't plan ahead, you're going to have to do some detective work.
This may help:
