8 Ways to Fix Bad Group Header BSOD Error in Windows

Bad Pool Header is one of the many infamous Windows shutdown errors, often referred to as the Blue Screen of Death. A bad group header stop error occurs when your hardware fails or some software interferes with your system’s normal processes.

It also appears when the computer does not properly manage system memory to run multiple processes. This causes your Windows to become unresponsive, forcing you to restart your computer. Also, you may lose unsaved documents and data as you force restart your computer. Now, let’s explore why this happens and how to fix it.

Possible causes of bad pool header stop error

There can be several reasons for the bad group header error. Here are some of the likely causes:

  • Interfering third-party apps: Some third-party applications are known to cause this error on specific computers.
  • Failed hardware: Old and faulty hardware may not run its process properly as usual. A faulty RAM or HDD/SDD can cause this error.
  • Antivirus: Some antiviruses can interfere with system processes.
  • Defective drivers: If your system cannot communicate properly with the disk controllers, you may encounter this error.
  • Bad disk sector: If your system files are on corrupt disk sectors, it can cause the blue screen error.

How to fix wrong pool header stop error?

There are several ways to fix the Bad Pool Header Blue Screen of Death. However, before attempting any solution, you should remove all but the necessary external devices connected to your computer.

Here are some common solutions for this problem.

Before you start

Although the Bad Pool Header stop error goes away after a reboot, you may experience this blue screen of death again at irregular intervals. If this happens, you can use the following methods to fix the problem.

However, if the Bad Pool Header stop error appears on every reboot, you may not be able to boot your Windows. If this happens, you should try starting your computer in safe mode to see if Windows starts.

Here’s how to boot into safe mode:

  1. Turn on the computer and turn it off halfway through startup. After three unsuccessful starts, your computer should enter the Windows Recovery Environment (WinRe).
  2. Click on Advanced options
  3. press Problem solving i Advanced options again.
  4. Select Startup configuration.
  5. In Startup configurationchoose Enable Safe Mode with Networking and reboot.

If your computer still won’t turn on, it might be a hardware problem.

Run the Windows Memory Diagnostic Tool

The Windows Memory Diagnostic Tool is a built-in Windows troubleshooter that checks your system memory. It also checks for physical damage to the system’s main memory (RAM). Because the bad pool header is a system memory allocation problem, try running this diagnostic tool.

Here’s how to run the Windows Memory Diagnostic Tool.

  1. Press the Windows hotkey + R to open the Run utility.
  2. come in mdsched.exe
  3. In the new window, select Restart now and see if there are any issues.
  4. After restarting the computer, the Windows Memory Diagnostic Tool it will scan your memory. (This process may take several minutes.)
  5. After the analysis is complete, the computer will restart automatically and display the test results.

If the test results show RAM errors, you should try changing the RAM. If you have multiple RAM sticks, connect the RAM sticks alternately to test which one is faulty.

However, Windows Memory Diagnostics only performs a surface-level scan of your system’s memory. You can also try scanning with more powerful open source applications like MemTest86+.

Update or reinstall drivers

Outdated and faulty drivers are one of the main reasons for Bad Pool Header or any other type of blue screen of death. The system uses device drivers to interact with the hardware, and driver problems can stop this process.

You can try updating or reinstalling your drivers. Follow the steps below.

  1. Press Windows + R to open the Run box.
  2. come in devmgmt.msc
  3. In the device manager, double-click the Disk controllers.
  4. Right-click on your device driver and click on Update option or Uninstall option
  5. If you uninstall the driver, restart your computer and the device driver will be automatically reinstalled.

You can also use Windows Update to update device drivers. Finally, if there is an exclamation mark next to any device driver, it may not be working properly. Please update or reinstall the driver using the above method.

Perform a system restore

System Restore is useful for fixing many different errors in Windows. It can also help fix the wrong group header error by reversing changes made on your computer that might have caused the problem.

Also, you can perform a system restore without booting into Windows. Here’s how to do it:

  1. Enter the Windows recovery environment using the method to enter safe mode.
  2. Click on Advanced options and select Problem solving.
  3. Click on Advanced options again.
  4. Select System Restore.
  5. Select a System restore point.
  6. Follow the instructions on the screen.

Run a CHKDSK scan

If your important system files are located on a bad disk sector (damaged part of a disk), your computer cannot access those important system files. The CHKDSK command fixes problems such as bad disk sector.

If this blue screen error is due to a bad disk sector, running CHKDSK commands can help fix it.

Here’s how to run this command without booting into Windows.

  1. Open WinRe using the method to enter safe mode.
  2. Select Advanced options > Problem solving > Advanced options
  3. Click on System symbol.
  4. Enter the following commands:
    Chkdsk /r /f /x C: (C: is the most common drive where the Windows system is installed, if it is installed on another drive, please enter it)
  5. Exit the command prompt and restart the computer.

Remove recently installed software

If the Bad Pool Header error started occurring after installing new applications or making changes to your hardware, remove them immediately.

No software is bug-free, and some poorly coded programs can interfere with your system processes. Some programs may also start behaving differently after you make major changes to your computer, such as updating Windows. You can try deleting these apps to see if that fixes the problem.

Also, third-party antivirus can also cause the Bad Pool Header blue screen.

Check the memory dump files

You can also check the memory dump files to see what caused the error. Memory dump files usually have records of what went wrong before the BSOD happened.

Here’s how to check memory dump files:

  1. Install the WinDbg Preview application provided by Microsoft.
  2. Go to the start menu and right-click Windbg.
  3. Click on Run as administrator.
  4. Click on Dossier header at the top right and select Open the dump file.
  5. In the right pane, click Browse.
  6. search %windir%\Minidump and open the minidump file.
  7. At the bottom, enter the command !analyze -v
  8. Find the Bad pool header stop error

The cause of the BSOD will be displayed in a “probably caused by” section.

You can also check if any of your drivers are malfunctioning and causing this error. You can run Driver Verifier to run all your device drivers to the limit and see if your Windows crashes again. You can then check the memory dump files to see which driver failed.

Clean install of Windows

If you still get the Bad Pool Header blue screen of death, you can try doing a clean install of your Windows operating system. However, before doing a clean install, if you can boot your Windows from safe mode, back up your data to an external drive.

You will need Windows installation media to perform a clean installation of your Windows operating system. You can create Windows installation media on any other PC and connect that device to your broken PC.

Then follow the on-screen instructions to clean install Windows from external media.

Finally, if the clean installation of the Windows operating system also does not fix the problem, then it is likely a hardware problem. It would be best if you take it to a service center for repair.
