I just finished reinstalling XP sp2 and my ATI 9500 is acting strangely. I cannot set AGP speed faster than 0X. When I select 4X or 8X (like was set before the reinstall) and reboot, it comes back to 0X. I have the most recent ATI driver, which I actually didn't have before, was using an older one. Do I just need to revert to an older driver? I am not overclocking or doing anything that would make me think I have an unusual setup. Asus p4S800 512MB crucial RAM, 2.4 Intel P4, ATI 9500 128 mb, etc. (will share more if it makes a difference...) Thanks!
