Look up these on Google.com and eject what they find.
Sometimes when I'm in the middle of doing something my computer will just go crazy and begin to open random programs (Task Manager, Word, Control Panle, etc). I have to wait a couple of minutes before it calms downs and sometimes one of the programs I'd been specifically working on has closed. My machine has an AMD Athlon processor, 512mb of memory, on an XP home platform. Any suggestions for preventing this occurrence?
