Don't install SP3 for XP, it's bugged to hell and will stop services and other things running.
The issue is ether with the DIRECT X DRAW of the drivers for the card.
What make and model of card is it.
Oh and installing SP3 for an issue with a non hardware bassed software, is a bit of an idiotic thing to do. As when you come to actually fix the fault and not cover it up, you will be left with a couple of problems. As most hardware drivers won't support SP3.
