I have 4 xp machines, one i use as a server with 4 external usb hardrives attached. I was sitting in front of the server when my mouse began to move on its own, hover over the date in the task bar, opening up my Gom music player, hovering over the pause button on my nero back up program, skipping all over the place, I heard myself saying, don't you dare. The children were watching and getting scared. I disconnected the mouse but it continued. I disabled the network adapter on the server, it continued. I launched notepad, and basically had a conversation with it. It was typing, I disconnected the keyboard, it carried on typing, I freaked out! What was it?
