Critical Structure Corruption - causes of a blue screen in Windows and how to solve the error

Critical Structure Corruption error with code 0x00000109 occurs when starting the emulation system and other software inside the operating system kernel. Its occurrence means that the kernel has detected damage to the data inside it.

Method of eliminating the error Critical Structure Corruption.

Causes of error

The kernel is the most important part of your operating system. It controls various tasks and applications on the PC - both software and hardware, for example, RAM and a processor. There are two types of cores - the microkernel and the monolithic core. The first has only basic functionality, the second additionally contains many drivers. In essence, this is a combination of software and hardware. The causes of the error are very large and wide. Therefore, you will need to perform many different solutions and see which one is right for you. The causes of the BsoD Critical_Structure_Corruption error in Windows are usually:

  • Damaged equipment (for example, a faulty memory card).
  • A driver that intentionally or accidentally changed critical kernel code or data.

As the reasons are clarified, it will not be so difficult to find solutions to the problem. Read on and find out how to fix the Critical_Structure_Corruption error in Windows 10.

How the critical structure corruption error appears

The most common cause of a blue screen is an outdated or damaged driver. It is displayed next to the CRITICAL_STRUCTURE_CORRUPTION error code and ends with “sys”. Here the solution is to update or delete this corrupted software. When you come across BSOD again, write down the name of the faulty driver to find out what it is for. For this there are many excellent sites that offer a complete description of the source. For example, Carrona: //

Open the link and enter your error in the search field. After that, the site will provide you with all the necessary information. First, you must determine which of the two types of drivers it is: Windows and hardware. If the damaged file in the search results contains a link, this is hardware; if Windows Update is indicated, this is software related to Windows.

Hardware drivers - used to run certain physical components of the computer, such as firmware or various system components. They ensure the smooth operation of various electronics on the PC. You can say that this is a hardware error if the Carrona table in the “Source” section contains a link to the site. Windows drivers, on the other hand, use only the OS. In most cases, the cause of the Critical Structure Corruption error in Windows are emulator programs and virtual machines. Other possible causes are:

  • Faulty equipment.
  • Outdated graphics card.
  • Damaged driver that affects OS master data.

Critical Structure Corruption - How To Fix

Alcohol 120%, Deamon Tools, MacDriver and Intel HAXM (Hardware Accelerated Execution Manager), according to the developers, are directly related to the Critical_Structure_Corruption error in Windows. If one of these programs is installed on your computer, update it to the latest version or remove it from the PC. After that, restart the PC and check if the error is fixed. When the blue screen reappears, go to the next method.

Update your graphics driver

In many cases, BsoD with an error is caused by faulty video card software. There are two ways to get the right driver for your video card: manually or automatically. Manual software update - you can update the software for a video card manually by going to the website of the manufacturer of your video card and performing the search for the latest current driver version. Be sure to select only drivers that are compatible with your version of Windows 10. Please note that if you are a laptop user, you should always contact the laptop manufacturer, otherwise you risk losing the advanced configuration functions that come with your video card. The automatic ways to update drivers include third-party software that scans the system, detects connected equipment, and compares the versions of installed drivers with the latest available on the Internet.

Memory diagnostic tool

As already mentioned, one of the possible causes of the problem is faulty hardware, such as a damaged memory card. Fortunately, you can easily check this with the built-in diagnostic tool:

  1. Windows + R / type mdsched.exe.
  2. You can select "Restart now and check for problems (recommended)" to check the status of the memory card right now, or select "Check for problems the next time you start the computer" if you are currently busy.
  3. A page opens showing the progress of the test and the number of passes it will complete in memory. If you do not see any additional errors, your memory card does not cause any problems.
  4. If you use a third-party diagnostic tool for the equipment you trust, run it and follow the instructions according to the setup wizard.
  5. Check the event log

Event Viewer will accurately indicate what happened when you had a blue screen of death with a Critical_Structure_Corruption error. Here is how you can verify this:

  • Windows + X / Event Viewer.
  • Open Windows Logs, check the middle of the window for suspicious events that occur around the time a blue screen error occurs. See if a particular program is responsible for your problem.

Removing the display driver

According to Microsoft, you can also try removing the display driver and restarting the computer. Here's how to do it:

  • Start Windows 10.
  • Simultaneously press the Win and X button.
  • Select a device manager.
  • Click on Display Adapters / Remove.

Restart the computer and check it for operability.

Equipment check (HDD, RAM, PSU)

Before proceeding to the troubleshooting steps related to the software, you must first check the hardware. Possible causes of BSOD and aforementioned structural damage are factors of various critical problems and many system failures:

  • HDD - use chkdsk (Command line> type: chkdsk c: / r and press Enter) to find and fix errors. or use a third-party tool. Make sure everything is connected correctly.
  • RAM - run a memory check or use MemTest86 to look for RAM errors. In case you have several flash drives, disconnect them one by one (leave at least one plugged in) and, thus, identify the faulty component.
  • Power supply - make sure all cables are connected correctly. In addition, if you recently added new hardware, make sure that it does not exceed the capacity of the power supply.


  • Right-click Start and open a command prompt (as administrator). At the command prompt, type sfc / scannow and press Enter.
  • Wait until the tool finds errors, and close the command prompt.

DISM is launched via the command line:

  • Right-click on Start and open a command prompt (as administrator).
  • Type the following lines and press Enter after each:
    • DISM / Online / Cleanup-Image / CheckHealth
    • DISM / Online / Cleanup-Image / RestoreHealth
  • Wait for the scan and close the command prompt.
  • Reboot the computer.

Check all drivers

In addition to applications that could not be integrated into the shell of Windows 10, we can not forget about the drivers. Faulty drivers are the most common cause of faults in Windows 10 today. Sometimes universal, but modern drivers can lead to the same results and break your system. So, you will need to experiment, find a suitable functional driver and, finally, disable the distribution of drivers through Windows Update:

  • Right-click the Start button and open the Device Manager.
  • Click on the view and turn on Show hidden devices.
  • If there is a faulty driver, find it in the list and reinstall.

If none of these methods helped you, you may need to completely reinstall the OS. If you have already encountered a similar problem and used a different method to solve it, tell about it in the comments under the article.
