RE: STOP: c000021a 0xc0000005 (0x00000000 0x00000000)

I found this..

0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATED
(Click to consult the online Win XP Resource Kit article, or see Windows
2000 Professional Resource Kit, p. 1561.)
This occurs when Windows switches into kernel mode and a user-mode
subsystem, such as Winlogon or the Client Server Runtime Subsystem (CSRSS),
is compromised and security can no longer be guaranteed. Because Win XP can’t
run without Winlogon or CSRSS, this is one of the few situations where the
failure of a user-mode service can cause the system to stop responding. This
Stop message also can occur when the computer is restarted after a system
administrator has modified permissions so that the SYSTEM account no longer
has adequate permissions to access system files and folders.

GoBack Causes a Stop Error C000021a {KB 316503} Win XP

Internet Explorer Maintenance Policies May Cause an Access Violation in
Winlogon {KB 318666} Win XP Pro
