After XP SP2, generic video drivers look terrible

I've got some no-name Windows XP PCs on our network that came from who knows where (no documentation, no manuals, no web site to download docs, drivers, etc.).  When I put SP2 on one of them, the video was just terrible ( 2 colors, very low resolution, couldn't change any of the settings, was basically on old VGA type of setting).  It's a standard video built in to the motherboard, no video adapter card or anything. The video drivers were just generic VGA, with no information to tell me what drivers I needed.  I uninstalled SP2 and the normal resolution returned. Question:  how do I update the drivers if I don't know anything about what's on the motherboard?

Hi Maharlika
Try SiSoft Sandra diagnostics and burn in utilities.

It will give you the motherboards manufacture/version/chipset. Then you can try a search on the internet if any drivers are available.
Have you tried looking on the motherboard for any manufacturer or model number. If you had a model number it is possible just putting a model number in to a search engine will return a manufacturer....i have tried that in past with unknowns.
