Error 0x00000109 (BSOD) occurs during the boot sequence and prevents affected users from using their PC. In most cases, this error occurs every time the system boots and renders the affected PC completely unusable.

The kernel is an important part of a computer’s operating system. During the boot process, it is the first program loaded into the protected memory area. Not only does it act as a bridge between the system resources and the PC user, but it also acts as a manager of memory, resources, and peripherals. Thus, you can see how a problem with the kernel leads to a blue screen of death.

What causes blue screen error 0x00000109?

Картинка с сайта: www.ircache.net

Damaged RAM: RAM can be corrupted and cause BSOD problems. RAM is important because it is needed to run applications and programs. Damaged RAM means the loss of an important component for Windows. To compensate for this, Windows stops important RAM-related processes. This solves the blue screen of death problem.

Driver problems: If blue screen 0x00000109 appears when Windows starts up, the most likely cause is a driver problem. Driver problems are one of the main causes of the blue screen of death (BSOD). Drivers perform several important processes, such as I/O management, security management, and plug-and-play memory detection. Thus, when a driver problem occurs, the system is forced to terminate an important process, resulting in a BSOD.

Software corruption/virus infection: Software corruption is one of the main causes of BSOD errors. Blue screen errors related to software errors most often occur when new software is installed or recently updated. Sometimes these updates are not compatible with drivers, leading to BSOD problems. A recent software change can corrupt the Windows registry, which only increases the likelihood of BSOD errors. If the software update is not done correctly, it will cause data files to be lost/damaged, which can cause BSODs. Damage or loss of important files is one of the main causes of BSOD.

As you can see, the error message is quite self-explanatory and suggests a couple of fixes you should try.

What Is Causing the Error 0x00000109?

The error is usually triggered when a device driver or third-party software modifies kernel data without authorization, leading to data damage or a critical kernel code.

The kernel is an important part of a computer’s operating system. During the booting process, it is the first program that loads into the protected memory area. In addition to acting as the bridge between the system resources and the PC user, it also serves the function of memory management, resource management, and device management. So you can see how a problem with the kernel leads to a Blue Screen of Death.

However, other factors can also trigger the error, including corrupt hardware memory, the incorrect usage of a kernel debugger tool, and a virus infection.

As the error 0x00000109 occurs, the operating system turns off several critical tasks so that the computer cannot be used. If the error is not resolved promptly, it can cause serious damage.

Since there are various factors that can cause the error, it is necessary to find out the particular cause and get it resolved. They include the following:

1. Driver Issues: You may have recently installed a driver that has affected the boot configuration data of your PC. Also, sometimes system drivers are installed incorrectly after a Windows update. In this case, what you have to do is to boot into safe mode and use the System Restore utility to revert your PC to a previous state when the issue did not exist.
2. Virus Infection: One of the most common causes of this error is when a virus tries to modify system kernel data. In such a case, a clean boot will be required, after which you should scan the system for viruses.
3. System File Corruption: Sudden power outages and improper shutdown or startup procedures, disk read/write errors, and virus attacks can lead to the corruption of system files. It is one of the common causes of the error in discussion. To resolve the issue, there are built-in utilities, such as SFC and DISM, that you can run. Another option is to do a clean install so as to reset every component of the operating system.
4. System Memory Malfunction: The blue screen error can result when a RAM memory module is not functioning correctly. The system then forcefully disables all important tasks that are associated with RAM. A module can get faulty as time passes or when there’s power outage. You need to check the system memory and make sure that it still works correctly.

Now that we have seen the various causes, it is time to go ahead and discuss how to remove the 0x00000109 BSOD. So please, keep reading.

1. Click the option that says, “Restart now and check for problems (recommended).”
2. Once the scan completes, your computer will restart automatically.

You now have to check the test results in the Event Viewer to determine whether you have a bad RAM module:

1. Press the Windows logo key to open Start.
2. Type ‘eventvwr.exe’ in the search bar and click on it from the results to open Event Viewer.
3. Open the Windows Logs folder and then right-click on System.
4. Click Find from the context menu.
5. Now type ‘MemoryDiagnostics-Results’ in the ‘Find what’ bar.
6. Click the Find Next button and then close the Find dialog.
7. Double-click ‘MemoryDiagnostic-Results’ listed in the Event Viewer window. If the message reads, “The Windows Memory Diagnostic tested the computer’s memory and detected no errors,” then it means that you do not have a faulty memory module. However, if there are some errors, then it means that one of your RAM modules may need to be replaced.

Fix 3: Update Device Drivers

If the stop error is caused by a problematic device driver, then performing an update can help resolve it. You can follow these steps to do it manually:

1. Press the Windows logo key + R.
2. Type ‘devmgmt.msc’ into the search field and then click OK or press Enter.
3. Look for devices that have a yellow rectangle with an exclamation mark in the middle. That shows that there is an issue with them.

Note: Keep in mind that any apps, drivers, settings, etc. that were not implemented on your PC on the date of your chosen restore point will no longer be present after the system restore is complete.

Fix 6: Run SFC and DISM Scans

If you try to boot into safe mode but still run into the stop error, it is an indication of system file corruption. You will have to open an elevated command prompt via the Advanced Options menu and run the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) utilities.

Follow these easy steps:

1. Insert your Windows installation media.
2. Restart your computer and press any key when the prompt appears.

Tip: In case you don’t have the installation media, you can still bring up the Advanced Startup Options Menu by turning on your computer and then holding the power button to disrupt the booting sequence. You will have to do this about three consecutive times. Afterwards, move on to Step 4.

1. After you’ve booted from the installation media, click ‘Repair your computer’ displayed in the bottom-left corner of the screen.
2. Select Troubleshooting > Advanced Options > Command Prompt.
3. In the elevated command prompt window, type ‘sfc /scannow’ and press Enter.
4. Wait for the process to complete. Do not interrupt the process. Doing so can cause some additional logical errors. Plug your PC to charge so as to make sure that the scan is not interrupted due to low battery.

Tip: System File Checker (SFC) replaces corrupted files with healthy equivalents from a locally stored folder.

1. Restart your computer after the scan is complete and follow Steps 1 through 4 to return to the elevated command prompt window.
2. To scan for and fix corrupt files using DISM, type in the following commands and press Enter after each one:

• Dism /Online /Cleanup-Image /CheckHealth
• Dism /Online /Cleanup-Image /ScanHealth
• Dism /Online /Cleanup-Image /RestoreHealth

Note: DISM downloads healthy copies of the corrupted files using a Windows update subcomponent. Therefore, connect to a stable network before initiating the process.

1. Once the scan is complete, restart your computer and see if the stop error 0x00000109 has been resolved.

Fix 7: Run CHKDSK

The CHKDSK (Check disk) utility will let you know if the stop error is caused by a corrupt HDD. Follow the steps below to run it:

1. Insert your Windows installation media (disk, USB stick).
2. Restart your computer and press any key when you see the prompt.
3. Wait for the Windows Setup screen and then press Shift + F10 to open the command prompt window.
4. Type chkdsk C: /f and press Enter.

Note: If Windows is not installed on the C drive, replace C: with the letter of the drive where Windows is installed.

1. Wait for the scan to complete.

Fix 8: Perform a Clean Install

If the fixes above have not been sufficient in fixing the error 0x00000109, then the option you have left is to refresh all Windows components and boot-related data by way of a clean install. There are two different ways to achieve this, namely repair install and reinstall Windows.
