re: stop error

by ThumbsUp2 In reply to error stop c000021a

Have you tried using Google to look up the stop error codes to see what they mean? I did, and this is what I found on another site.

I would suspect that either a bad hard disk (run chkdsk) bad RAM , or a third party boot loader or backup utility (goback) is the cause.

http://www.aumha.org/a/stop.php
0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATED
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. 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 as a result of malware infestation or 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.

0x00000050: PAGE_FAULT_IN_NONPAGED_AREA
Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).

(You recieved this error during setup)

I would start using just one stick of RAM
If you still get the errors, try with another single stick.

Boot to the recovery console and run chkdsk on the hard drive.

It can also be an application error

by w2ktechman In reply to error stop c000021a

that does not shut down properly. Try running the user profile hive cleanup utility (uphclean) from MS (free download).
