Hello William, back up your registry.

Are you using XP?
Backing Up Your Registry- Go Here and download ERUNT
(ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.) - Install ERUNT by following the prompts
(use the default install settings but say no to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later) - Start ERUNT
(either by double clicking on the desktop icon or choosing to start the program at the end of the setup) - Choose a location for the backup
(the default location is C:\WINDOWS\ERDNT which is acceptable). - Make sure that at least the first two check boxes are ticked
- Press OK
- Press YES to create the folder.
