Any of you guys have experienced the kind of problem?

Any idea?

Thanks in advance.

Try booting in Safe Mode first from the F8 menu.

Check the following registry key to see if its different

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
C:\Windows\system32\userinit.exe,

You may need to replace the winlogon.exe from the Recovery Console.

If you can, post a HiJackThis log

Also here is a screenshot from Sysinternals Process Explorer showing the threads in the winlogon.exe process (XP Pro SP3)
