Check if this software bug applies to your system:

An incompatible version of GoBack (included with Symantec System Works) will cause this issue. It will be necessary to remove this version of GoBack. See Microsoft article 316503 for instructions to disable and remove GoBack.

Older versions of Internet Explorer version 6 can cause this issue. Apply the latest updates to IE6 or upgrade to the current version of IE (Microsoft article 318666).

Use Last Known Good Configuration
8
    Add    Flag
solution icon

If you are unable successfully boot into Windows because of the fatal error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:

  1. Reboot the computer.
  2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
  3. When successful, you should see a black screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.

Check if you are using the latest hardware drivers, especially the chipset and video drivers. Older drivers are a common contributor to BSoD issues.

You can use a product like Driver Genius or Radar Sync to verify you have the latest drivers and help keep all your drivers up-to-date. If you're comfortable with driver installations, you can individually find and install current drivers.

A some of the most popular driver download sites:

Uninstall the Last Install
6
    Add    Flag
solution icon

If you can get the system up for more than a few minutes or can use safe mode, try removing the last installed software application or driver.

For removal of an application (Windows 8+)

  1. Press the Windows Key and X together, then  Control Panel, then Programs and Features.
  2. Select the software to uninstall and select Uninstall.

 For removal of an application (Windows 7 & Vista):

  1. Click on Start, Control Panel, then Programs and Features.
  2. Select the software to uninstall and select Uninstall.

For removal of an application (Windows XP):

  1. Click on Start, Control Panel, then Add or Remove Programs.
  2. Select the software to uninstall and select Remove.

To disable a driver:

  1. Bring up the system information dialog:

    On the keyboard, press the Windows key + Pause/Break.

       or

    Select Start, right click Computer and on the drop-down, select Properties.

  2. Click on the left side option Advanced system settings (7/Vista only).
  3. In System Properties, select the Hardware tab, then click on Device Manager button.
  4. Find the hardware/driver of interest (you may need to expand a choice at the "plus" graphic) and double click the choice.
  5. Select the Driver tab. Here you can perform a number of actions such as update the driver, roll Back the driver to an older version, disable or uninstall the driver.
  6. Click OK to exit, then close the Device Manager and other previously opened dialogs.

Fix Improper File Restore
5
    Add    Flag
solution icon
If you just restored from a backup, the backup may have failed to save key system files that were in use at the time of the backup. As a result, the restoration would restore some system files, but not others. This can cause different versions and/or a failure to repair some damaged system files.

This is a bit of a mess, and not easily solved. If you have a another complete backup, you might try it. You might also try using the Recovery Console to restore system files.

Restore From Backup or Image
5

If you know the hardware is good and you have a current backup or image of the drive, you could reformat the hard drive and start over. This is often the last resort when all else fails, as you will often lose your latest settings and important data. If you have a spare drive, it may be worth it to install the drive in place of the first drive and do a fresh install of Windows. This will help confirm if this is a hardware or software issue (unless the original system drive is the source of the problem).

  technical details

A user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed. The operating system switches to kernel mode since Windows cannot run without WinLogon or CSRSS causing this fatal error.

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 specifies a string that identifies the problem.

Parameter 2 specifies the error code.

Parameter 3 is not defined.

Parameter 4 is not defined.
