graphic drivers? if so go to the website where you got the card from and they have downloads to update. if not im guessing to to the site of wherever made what u want to update and they should have download updates
ditto i had to update mine you just go to the website of your graphic driver like for example mine is ATI radeon so i went to the ati website and downloaded the new driver for my type of card and just uninstall your old driver then install the new one
^what he said, but these days, in XP, you can just update the drivers, so in case they dont work, you can revert back to the old drivers..
Either go into the manufac. site or go into Windows Update - Sometimes you can get your updated drivers from there too
