This is likely a System Registry corruption.
I am pasting the Microsoft Help information below that will guide you through selecting the Last Known Good Configuration Settings option, but if you are comfortable with simple instructions, then do the following:
1. Start up your computer from a powered off state
2. Immediately begin rapidly tapping the F8 key at the top of your keyboard. Do not hold it down...tap..tap..tap it continously until the Windows Startup Menu displays. Then use your arrow keys to select the 'Last Known Good Configuration' menu choice and press Enter. Hopefully this will solve your problem. If not, let me know. Follow the instructions below if you want more in-depth instruction on performing this repair.

Thanks for your help. I had problems with the unistallation of Roxio 7.5. I had taken off all the components and still nothing worked. What I did is that I installed the Roxio 9 as a trial and probably that restored the drive, plus I did other things that I don't remember how I was able to restore the drive. Anyway, I am glad that I couyld do it by myself.
