black logon screen without other bad effects RRS feed

  • Question

  • hi, I'm experiecing a strange thing

    when I start the computer, the logon screen is black. 

    however, it seems except the background has no color, there is no other bad effect.

    because when I move to the place where the password input area should be, the mouse turn into cursor, and then I can input the password.

    after loginning, the screen displays color.

    so it is totally different with other black screen incident.

    though I can login in till now, what if one day the system goes wrong, I can see nothing different since the screen is black. how can I fix it.

    last time it appeared was after a windowsupdate, I thought the reg is affected, so the complete reg files in config dir were replaced by the version few days ago, it worked. but this time, even this method will not work

    please kindly give your advice.

    I don't want to do a reinstall, and I do not have restore points. no install discs, so no in place upgrade. the last correct configuration do not work. safe mode HAS colors.
