2 things you can do:  you might have to boot in safe mode

1.     Open Windows Explorer and navigate to C:Windows\System32 folder. Locate the file msgina.dll and move it to d: or some other location. A new copy of this file will be extracted by XP

See if the problem persists. If yes, open Command Prompt window and type in:
"SFC /PURGECACHE"
Then, "SFC /Scanow"

2.     Go to Start/Run/Regedit and navigate to:

HKEY LOCAL MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon

In the right pane scroll down to UIHost. Double click it and type this in under Value Data: logonui.exe
