Hi Kevin,
To boot to Command Prompt continually hit your F8 key while rebooting. This should take you to a menu where you will be given the choice of booting to a command prompt. Once at the prompt type in Scanreg /fix.
Will this work? Only God and Bill Gates knows.
The registry is a system data base that holds information that tells your pc how to boot up and what programs to load on bootup.
Hope this will help you. Good luck.
Gerry
