Video card driver

Hello,
Hello,
I just wanted to say that if I 'offended' anyone by asking a question im sorry...I actually resolved the problem on my own but I didn't know it was a must to say please/thank you...even though I dont think my post was rude at all, im apologizing since it seemed to be misinterpreted. My previous post is below...:
I reinstalled windows xp and lost my video card, i dont know which one i should download...I dont know much about computers so i might need a driver too?? I just got sound back after installing the realtek :) only problem is the video card now.
