Out of curiosity do you have Norton Antivirus installed on your computer!!
also do you have a Zip drive!!
PS ne of your programs is checking for a floppy
drive; I'd guess antivirus.You may have an option to
tell it not to do that.
Try disabling the floppy controller in your Device Manager.
If that doesn't work, see if you can disable it in the bios.
If you need more info, please repost with the type of computer
you have, what apps are running at shutdown, and what else
