After upgrading my brother's computer (celeron 566 @ 850 Asus P3V4X) to an AMD Duron 800@800 in a shuttle AK12 MB I have noticed a lot of skipping or as my brother calls them "mini freezes" in all his games and and multimedia programs. I noticed this when the duron was in my comp. but dismissed it since I'm not a big gamer. I have the latest NVidia detonator drivers (GF 2 MX400) and the latest 4 in 1 drivers installed in a fresh install of windows with the all the updates microsoft deemed necessary. Has anyone else run across this?
