How to Solve: Critical Windows Error 0x00000019

Several Windows 10 users have contacted us with questions after their activities were frequently interrupted by critical BSOD (Blue Screen of Death) crashes showing error code 0x00000019.

Most of the affected users report that the problem occurs randomly in their case (with no apparent reason). Although this type of error is much more common in older versions of Windows (Windows 7, Windows, and 8.1), we were able to identify several cases where it occurs in Windows 10.

This IR Cache article shows you how to troubleshoot this Windows error.

What causes the critical Windows error 0x00000019

This error indicates that a process has entered the memory pool and failed to exit correctly, damaging the memory pool header.

This error may be caused by the following:

Antivirus software: Sometimes some brands of antivirus software can corrupt system memory and cause this error.

Driver conflict or outdated drivers: Sometimes device drivers are misconfigured, corrupted, or outdated. This can also occur after upgrading or downgrading Windows from a newer to an older system.

Faulty RAM: The most common cause of this error is a faulty RAM module that periodically produces read/write errors. In this case, it is recommended to analyze the system memory and replace the faulty RAM module.

How to resolve the critical Windows error 0x00000019

Execute a CHKDSK scan

  1. Start by pressing the Windows + R key combination to open the Run dialog box and type cmd.
  2. Press Ctrl + Shift + Enter to open the extended command prompt.
  3. Once on the extended command line, type the following command:
    chkdsk /f
  4. Then press Enter to start the offline scan.
  5. Once the CHKDSK scan starts, the CHKDSK function starts its checks.
  6. Depending on the size of the selected drive and the amount of data stored on it, the process may take anywhere from a few minutes to half an hour.
  7. If everything is OK, you will be informed that there are no problems detected.
  8. However, if the CHKDSK scan detects any errors, it will try to fix what it can.
  9. Be sure to reboot your computer and see if the problem is resolved the next time you start your system.

Also, some bad sectors on your hard drive can affect a critical service, causing the system to produce a shutdown error like the one you see now.

Therefore, we recommend performing a CHKDSK scan to increase your chances of fixing error 0x00000019. Don’t worry, you won’t damage your computer by running this scan.

Check the RAM

  1. Click the Start button.
  2. Type Memory Diagnostics Tool in the search box.
  3. Right-click on the Memory Diagnostics Tool.
  4. Select Run as administrator.
  5. Follow the instructions to start the diagnostic process.

If the error is caused by faulty RAM, it is best to check the RAM using the Windows Memory Diagnostic Tool. To do so, follow the procedure described above.

Disable or uninstall any third-party programs

Some brands of antivirus programs and other third-party utilities can corrupt the system memory and cause this error 0x00000019 to be displayed. The third way you can try is to disable real-time protection.

This depends on the third-party antivirus package you are using. However, you can usually do this directly from the corresponding menu in the system tray.

If this makes no difference, uninstall all antivirus programs running on your computer and restart it.


A blue screen error is essentially a protective measure taken by the Windows operating system to prevent serious damage due to a critical hardware or software failure. It protects other hardware and software components of the system from damage. However, BSODs occur suddenly and may occur without any indication. Therefore, it often leads to a data loss situation.

To avoid BSOD errors such as BAD POOL HEADER 0x00000019, you should actively monitor the state of your hard drive, update your Windows operating system and drivers, and optimize your drive from time to time to improve performance.

And to avoid losing data due to such errors, create at least two backups – one local on an external drive and one in cloud storage. Use third-party data recovery software to recover files that are missing from the backup or have been lost due to BAD POOL HEADER 0x00000019 error.

A pool header problem is a memory allocation problem in Windows. Device driver problems are probably the most common, but they can have many causes, including bad sectors or other disk write problems, as well as problems with some routers. (Theoretically, RAM problems could be suspected of memory pool problems.)

This error means that you may have to revert back to your PC's previous configuration. Turn off your PC by pressing and holding the power button, then wait and press it again to turn it back on. When your PC reboots this time, you can  choose how to start up.
