Hello and welcome to Tom's Hardware Forums.
Specific drivers for this board are hard to track down without sending you to one dubious download site or other so I'm going to recommend this site for generic drivers for the Inter 945 chipset which should do the trick. Intel is the safest site in the circumstances so go to http://www.intel.com/p/en_US/support/highlights/graphics/945gm and follow the links to the XP section.
Post back (only one post, please ) if you still need some help but start a new thread of your own - this oldie is being closed.
