youve got to turn off some of the "junk".
One thing is the extra "eye candy"...all the video stuff like scrolling menus and shadows under drop boxes etc....I usually leave shadows under the icons etc but I turn off most of that list.
I cant remember where those settigns are off the top of my head but someone else will chime in.
Also, there are lots of services running on there that dont need to be...gay stuff like "alerter" "BITS" "portable media serial number" "wireless zero configuration".....a whole long list of stuff taking up resources for no reason...so you need to turn the extra junk off.
go here
http://www.blackviper.com/WinXP/servicecfg.htm and check it out....I pretty much use his "safe" config on my xp machines....but I leave system restore on which he turns off.
Anyway, that is a good way to give it a lil more snap.
