If I leave my computer on for any legth of time, which is always, all of a sudden any program I run gets real "jerky" and if you move the mouse around it is "jerky" also. Like min freezes. I am on a Sony Vaio running Win XP Home. I wrote Sony and of course they said it was a bug in XP. If I restart the computer it goes away, but it is really annoying. The first time it happened I thought my computer was fubar!
