    Had problems with original xp professional. Reloaded
    using recommended upgrade. While running message came up
    saying:

    signature for xp upgrade is invalid
    error code is fffffdda
    failed to install product catalogs

    rebooted several times and went back to screen showing
    reloading software. then the screen goes blank.

    what is happening? Was my harddrive wiped out? If so,
    can it be restored by computor tech?

    Help
