SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

STOP: 0x0000007E

 
  Description  
     
 

Windows stopped for an unexpected error. In some cases a device driver may be identified, but the issue might not be related to this driver.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

 
   
  Sample Screen  
     
 

A problem has been detected and Windows has been shut down to prevent damage to your computer.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Microsoft has issued a hot fix (a special update) to fix this issue:

In Windows XP SP2 only, install this Microsoft hot fix to correct the issue (Microsoft article 900485).

In Windows XP, if when removing a CardBus Compact Flash (CF) adapter the pci.sys driver faults, you will need to install the current XP service pack (Microsoft article 839641).

In Windows Vista, pre-SP1, if this error occurs after waking from sleep or hibernation with the driver usbhub.sys, you will need to upgrade to the current Vista service pack (Microsoft articles 929734 and 930311).

Free Up Disk Space
8
    Add    Flag
solution icon

The system disk (typically C:) may be full. We recommend at least 1 GB of free disk space be left on the Windows system drive at all times. To get additional space:

  • Remove deleted files (right-click on the trash-bin and select Empty recycle bin)
  • Remove unneeded files, such as browser cached files.
  • Move files to another drive or media
  • Compress or Zip large files to take up less space
  • Transfer the system to a new larger drive

Several software products that can help clean and remove unneeded files are Fix-It Utilities Professional and SystemSuite Professional. If you need to move or copy a partition or entire drive, you could use Partition Commander or similar product.

Install the latest Windows software updates. Don't forget to check for non-critical updates too!

To manually get updates, open Internet Explorer (you can't use a non-Microsoft browser for updates).

For IE 8 and later: Click on Safety, then Windows Update. Follow the instructions.


 

For IE 7 and older: Click on Tools, then Windows Update. Follow the instructions.

Check if this software bug applies to your system:

In Windows XP, old versions of Logitech iTouch or Mouseware software are incompatible. Remove or upgrade these drivers.

If you are attempting to use Roxio Easy CD Creator 5, it is not compatible with XP or later Windows versions. Uninstall or upgrade to a current Roxio version (Microsoft article 310628).

Fix Defective Hardware

Confirm the hardware is working correctly using a hardware diagnostic program. If you suspect a specific hardware item, such as memory stick or video card, try replacing it with known good hardware.

Don't overlook the possibility that hardware was not installed correctly, especially anything you installed just prior to the problems starting. Make sure all cards and memory are securely seated in their slots. Verify disk drive cables are properly connected and are not loose.

Several software products that offer an extensive range of hardware diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

If you just installed new hardware, confirm it is really compatible with the Windows. Use Windows compatibility page for newer Windows. The XP compatibility page was removed from the Microsoft site in Nov-2010.

Get the Latest Drivers

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.

Update the BIOS and BIOS Parameters
6

Check with the PC manufacturer if you're using the latest BIOS or not. If not, update to the current version.

A few of the manufacture's download or support links for a motherboard/BIOS update:

    If the BIOS is current, it's possible bad BIOS parameters are causing the problem, especially if the memory or CPU settings are overclocked. The BIOS parameters are stored in CMOS memory. The best way to reset the BIOS parameters is to remove the CMOS battery. To do this:

    1. Unplug the PC, and open the case.
    2. Locate the battery on the motherboard - typically a silver coin cell.
    3. Remove the battery and note if the plus side is up or down, so you can reinstall it later the same way.
    4. Wait at least 1 minute and reinstall the battery.
    5. Attach power and power up. Typically a BIOS warning message will indicate CMOS was corrupted or changed and it may require you to go into the BIOS setup to set the time and date.
    6. Proceed to boot Windows and see if this fixes the issue.

    Some BIOSes have options to enable/disable caching and/or shadowing. If the options are available, disable caching and shadowing. Most newer (2005+) systems do not have these options. There are many BIOS makers and customized versions of the BIOS, so you may have to enter BIOS setup and look a bit to find these options. Typically you press a key like Esc, Del, F1, or F2 before Windows starts (almost right after you reboot) to enter BIOS setup. Consult your computer manual for details. The setup key can also be found in our BIOS access list.
