I recently had a "Security Alert" when I was on the internet. I immediatley turned the computer off. Now when I start windows I get the "chess Piece" symbol and my logon name but when I click on the symbol windows does not start up. I get the message "Loading Profile setting" but then I get an immediate message that windows is shutting down and my profile settings are being saved. I have tried using the "Restore" utility but I still have the same problem.

Can you boot into safe mode ?
(Press F8 just before Windows starts to load)

I am not able to start up in "Safe Mode". I get the same response from windows.

Did you try a Windows repair install ?
See this page for available Windows XP Repair possibilities you could try ...

I did the Windows repair install and I also copied the appropriate files from
C:\windows\repair to c:\windows\system32\config\software
C:\windows\repair to c:\windows\system32\config\system
C:\windows\repair to c:\windows\system32\config\sam
C:\windows\repair to c:\windows\system32\config\security
C:\windows\repair to c:\windows\system32\config\default

None of this worked.
