I recently fresh installed winXP home on my P3 733MHz with a GF2MX400 in it. My PC slow down tremendously just like previously I was using win98 with active desktop on. So, I disabled the active desktop on my winXP. Yet it is still slow. Even the screensaver (Aquarium) is slow. It is smooth for about a second or 2 then paused for a while then moves agian for a second or 2. I've also disble some of the services which is not required and make sure there is no background application running. Even in games like Hot pursuit2 where they show the intro, Fraps measured about 45fps but I can see a lot of frames was skipped. So, any idea what I should do about it to make it smooth?
