Just follow these steps. slide 1 of 4 What Does Stop 0xC000021a Error Code Mean? The Windows 0xC000021a stop error code occurs when critical system processes fails to run, like when the Winlogon.exe and Csrss.exe processes have stopped fatal system working. The Windows NT kernel will detect it and raised the stop C000021a fatal system error message or bluescreen (BSOD). It occurs because of a faulty third-party Graphical Identification and Authentication (GINA) DLL which is a replaceable DLL component that Winlogon.exe loads. There are several causes of bluescreens with the stop c000021a error code. Among fatal system error them are the following: Mismatched system files have been installed. A Service Pack installation has failed. A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.
