The causes of ntdll.dll error messages can vary greatly. However, most ntdll.dll errors result from a corrupt or damaged version of the ntdll.dll file itself, corrupt hardware drivers, or issues between Windows and other programs.  Third party software programs that have been installed on your computer are almost always the cause of ntdll.dll errors.
