disable the 'scan floppy on access' in nortons. I've seen that happen before, and that can cause it at times. basically, windows gives the park/shutdown command to the hardware (floppy drive), norton sees this as access and tries to scan. usually what will happen is it will shutdown after some 20 minutes or so.
If you argue with an idiot he will drag you down to his level and beat you with experience.
