I'm running XP on my toshiba, and for a couple years the fan has been pretty loud. Well now, it's actually overheating and shutting down. It's doing it when I try to run disk defragmenter, disk cleanup, or my Macafee virus scan. Everything is moving slowly, and I was trying to clean things up. Any suggestions to stop the unwanted shutting down? I've actually had the fan changed out a couple times...
