Recently replaced a 9700 pro card for a 9800 pro in my sons' xp system. I also changed the driver from 5.11 to 6.4 catalyst. No matter what drivers I use, the system will not remember any changes to the resolution settings. That is, the minimum is 800x600 and if i try to set it to any thing else, after reboot it's back to 800x600. Anyone got any ideas
