I just purchased a hp pavillion ze2000. It has a amd mobile sempron processor, 40G hard drive, 256MB ram. However, when I open more than one program at the time the speed of swapping is horrible. It is loaded with win xp. I had an old hp with win 98, that seemed to be faster with multiple programs, is there any tweaks, or anything else I can do? Please help. I dont want to be stuck with this, I love everything about it but this.
