Fatal system error in windows 7

I recently have gottent his error message when I restarted my computer.

STOP: c000021a {fatal system error} the initial session process or system ended unexpectedly with the lock status 0x00000000 (0 xC0000001 0x000108d0). The system has been shut down.

I have read many guides, but nothing has worked.

Running in safe mode does not start.

using the chkdisk and run other tools in promtp CMD when you do a repair mode is not solve my problem.

I want to fix it because I don't want to reconfigure my tools on the computer.

If the problem is caused by bad registry data and then restore the registry files manually to an earlier point could solve the problem. The process is complex and requires some careful typing. You may reset your password to an earlier value.
1. start the machine in Repair Mode.

(irrelevant) 2.4

5. Select the command line in the menu.
6. identify the correct drive letter for your Windows installation. It could be one drive other than c, but it will not X:. You do this by typing commands
DIR C:\Win*
Dir D:\Win*
dir E:\Win*
until you find the Windows folder.
I'll call this "Q:" drive
7 type these commands:
CD /d Q:\windows\System32\config
xcopy *. * Q:\MyRegBack\
CD RegBack
8. review the dates of the software, system, and SAM files. The files created before or after that is your problem?
9. If they were made before the problem appeared, you can then type these commands:
copy software / y...
/y copy system...
/y copy Sam...
(the two points are part of each order)
10. restart normally. If things don't work then you can go back by copying files from the original register of Q:\MyRegBack to Q:\Windows\System32\config.

    Check and see if the default Microsoft GINA has been replaced, to edit the registry, you have to mount the boot disk not in another machine to Windows or use a disc like UBCD4Win PE.  See here for easy to follow instructions on how to modify remote installation no Startup registry: http://www.rwin.ch/xp-live/regedit.htm

    If GINA is ok, you can try to restore the computer to an earlier date, or you might have to do and an upgrade on the spot (relocation) of the operating system.

    My husband must have some kind of bug in his computer as Kaspersky Internet Security, when he went on the internet, gave him a choice to block something that was causing a problem.  When he clicked "Block" - he got the BLUE SCREEN!  Is anyway for him to cancel it and save all her pictures on his computer?

    It has a Dell Dimension 8400 computer about six years.
    Sorry to bother you, but this time we did shut down his computer and restarted everything was fine.  Apparently he had clicked on something like 'do not allow' or however its formulation that I do not see.  So now we have to probably save photos and things out of his computer and take out the drive to reinstall Windows XP because there still be some sort of bug in there because we are getting popups saying some program are eager to enter the passwords section.  I don't know much about it but try to fix it!

    I looked into Kaspersky and ran a browser Configuration and analysis of the vulnerability in his computer and found that there was a kind of 'control popup' in Internet Explorer that had been added in the settings of the pop-up window. -I deleted who.

    I saw a setting in Kaspersky has been changed by default (they say "changed by the user, but did not change). -I have put all Kaspersky setting at default.

    So now, we hope the computer that my husband will work very well in the future because it's good now, even after rebooting.

    Now, we will have VERY serious about all of his photos on his backup external hard drive!

    If we have more problems with that, I'll be back but for now, everything is GOOD!

    Original title: c000021a fatal system error - help please!

    My son has bad closed my laptop just by holding down the power button without closing the first and next time I tried to use it, he began to start as she normally does, but instead of going to the login screen after screen of 'Windows', a blue screen came that said: "STOP: c000021a {fatal system error} the windows connection ended unexpectedly with status 0xc0000005 system process (0x00000000 0x00000000).» The system has been shut down. I tried to start it in safe mode, and it just goes back to the same screen. I have a Dell Latitude 110 L with windows xp and service pack 3. No norton. Can I do to solve this problem?

    Three things come to mind.

    Your file system got corrupted (usually not too big of a deal of difficulty) and XP can not simply to find the necessary files.  Which can sometimes occur if you use the power button.

    Certain older versions of Norton will sometimes cause this problem of corruption after the reception and therefore updated my application (stupid Norton).

    Your winlogon.exe or explorer.exe has been quarantined (actually deleted) by your AV software

    You must first start on your CD in the XP Recovery Console and check the integrity of your file system using the command chkdsk /r program.

    If the chkdsk /r did not do so, we use the Recovery Console XP replaces your winlogon.exe and explorer.exe.

    You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.  These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

    Put your XP CD in and start on it and keep reading below.

    If you are not sure what kind of CD you or "looks" right, we can make a bootable CD of XP (media without required P) Recovery Console.

    When you start on the CD, follow the instructions:

    Press any key to boot from CD...

    Installing Windows... going to pronounce.

    Press 'R' to enter the Recovery Console.

    Select the installation that you want to access (usually 1: C:\WINDOWS)

    You may be asked to enter the password (usually empty).

    You should be in the folder C:\WINDOWS.  It's the same as the

    C:\Windows folder that you see in Solution Explorer.

    The Recovery Console allows base as file commands: copy, rename, replace, delete, chkdsk, fixboot, fixmbr, cd, etc.

    For a list of the commands in the Recovery Console, type help at the command prompt.

    Start by checking the integrity of your file system by using the chkdsk command.

    In the command prompt window, run the chkdsk command on the drive where Windows is installed to try to fix any problems on the afflicted player.

    Running chkdsk is fine, even if he finds no problem.  It won't hurt anything to run it.

    Assuming your boot drive is C, run the following command:

    CHKDSK C: /r

    Let chkdsk finish to correct the problems, he could find.  It may take a long time for chkdsk complete or they seem to be "stuck".  Be patient.  If the HARD drive led blinks always, chkdsk is something.  Keep an eye on the amount of the percentage to be sure that it is still making progress.  It may even seem to go back sometime.

    You must run chkdsk/r again until it finds no error to correct.

    Remove the CD, and then type "exit" to exit the RC and restart the computer.

    You have not to set the BIOS to boot the disk HARD since the CD won't be.

    The system has been shut down.

    Twice I was able to get in "Safe Mode", words ran across the screen as they will normally in "Safe Mode", but both times the computer restarted again.

    I tried to launch a repair several times with a borrowed Windows XP disc, every time after the repair, he says that the system contained errors, but had been repaired, but the problem persists, just guard computer restart, stop with the error again in a loop.  Hope this helps.

  • I get a msg of error: Stop: c000021a {fatal system error} subsystem of the system

    Hello, Hello...

    I have an error when whenever I start my laptop and it will return to market after a few seconds after that boot then BSOD (blue screen of death) appear with msg like this...
    STOP: c000021a {fatal system error} the process window system subsystem ended unexpectedly with status c0000005 (0x75e9ad15 0x0052f240). Then the BSOD stuck there and forcing me to press the reset button to restart the laptop... What is the cause that happen to my system of the laptop? Sometimes it restarts automatically when I try to install a new version of the Media Player Classic player, open a video in Media Player Classic, open the Opera web browser and some kind of emulator PSP (Playstation Portable).

    In addition, I noticed there is some sort of process that runs without warning when I try to monitor using Process Explorer, the process is "wscript.exe". before that my laptop is not running this kind of process, but it in courses run once I started a laptop after I installed Dev C++ application, DOSBox (emulator of game back) & Opera web browser.

    How can I solve this problem?

    I use

    Acer TravelMate laptop computer
    Intel Celeron
    Microsoft Windows XP Professional SP2

    p/s: sorry for my bad English.

    You get the error because Winlogon.exe or Csrss.exe is a failure.  The cause could be installed incompatible system files, program service pack installation has failed, the backup did not work right, or an incompatible third-party program has been installed.  From the sounds of it, you'll first want to take a look at the programs that run at startup, as is usually the last of those above problems that caused the problem.

    I hope this helps!

    This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

    Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.

    Solve the problem

    Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

    Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

    If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the Windows Advanced Options menu that results, select the last known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

    Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

    Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.
