    Does the computer blue screen every time you boot up? Any new programs installed recently?
    If the problem started occurring after a new program install then you could try booting up into safe mode and uninstalling the program. On boot-up hit the F8 key and select safe mode. If not then I would try doing a system restore to a point in time before this problem started occurring.

    Let me know how it goes or if you have more information regarding the problem.

    My solution was to start in OEM dvd and to copy ntdll.dll from the x:\Windows\system32\ to c:\Windows\system32.
