Hi chezzy. This is quite an old motherboard, and I can't find any drivers later than Windows 2000 click here. I think probably Windows XP itself installs the latest available drivers. I rather suspect your graphics drivers. Games can be very picky about graphics drivers and it's not uncommon for the latest drivers to give problems with some games. You may find the game makers have a patch for your games/graphics combinations, or you may find that reverting to an earlier graphics driver is better.
