    Black screen after login for some seconds, then back at logon screen!


    Hi people, i've just registered to this forum to ask you about this, Since i've made a registry defrag with TuneUp Utilities (which probably has gone wrong), when i reset the computer, and I logon to my user, it shows a black screen, then back at the logon screen. If I do it again, the user doesn't show up anymore!
    It happened three times already, i had to make new users, and i'm sick of it. Any ideas of what could it be?

    Welcome!

    Yet another case of registry defraggers causing harm. In the future, you know now to stay far away from them.

    I suggest a system restore to get to a point before TuneUp utilities. If that doesn't work, it will be time for a repair install.

    Good luck!

    I've gone back to a point before TuneUp without any luck.
    I'm looking for my Windows 7 DVD, but, is there anything I could do before trying the repair instalation?

    Not that I know of, sorry.

    Maybe others know of a way, but until they post, I would advise keep looking for the DVD.

    Boot in safe mode and attempt to load the registry form a back-up.. if there is a back-up.
