Bad Pool Header is a common blue screen of death error that can occur in all versions of Windows, including Windows 7, Windows 8, 8.1, and Windows 10.

There are many causes of bad pool header errors , including physical memory problems, corrupted Windows registry entries, viruses & malware, or incompatible apps.

Bad pool header error codes are often temporary, and a simple reboot fixes the problem. However, sometimes the error can be more permanent, which can be a major headache for computer owners.

3. Disconnect All Connected External Devices Except Your Keyboard And Mouse

Sometimes, when you connect a new external device, and it’s not fully compatible with your Windows computer, it may create a Bad Pool Header BSOD error.

To test, temporarily disconnect all connected external devices plugged into your computer, except your keyboard and mouse. Then, reboot your computer to see if the error persists.

If this BSOD is gone, one of those external devices is the cause. To identify the specific device, reconnect them one by one until you find it.

4. Undo Recent Changes On Your Windows Computer

If you recently installed a new program on your Windows PC and Bad Pool Header occurs,  uninstall it. That program may conflict with other installed apps on your computer and lead to this type of BSOD.

To uninstall apps in Windows 10, navigate to Settings -> System -> Apps and features.

Uninstall Windows 10 apps and features

Search for the application that you have recently installed, then select it and click on the “Uninstall” button.

Tip: In some cases, third-party antivirus programs can cause this type of BSOD. Therefore, you can temporarily turn off your third-party antivirus and reboot the computer to see if the issue persists. If this move helped to correct the problem, you should consider removing that antivirus software from your computer and search for a replacement.

5. Scan And Repair Corrupted Windows System Files

A damaged Windows system file can also lead to a Bad Pool Header BSOD. Perform the SFC command to scan for corrupted files on your computer and repair them automatically.

To get started, press Windows + X, then press A and choose Yes to launch the Command Prompt application with the administrator account.

In the Command Prompt window, execute the following command to scan all the Windows system files and repair them automatically if any corruption is found.

SFC /scannow

Command Prompt: sfc /scannow command

This process may take a while to complete. Please don’t restart or shutdown your computer while the process is working.

6. Update Or Reinstall Windows Drivers

As recommended above, you can use BlueScreenView or WhoCrashed tool to figure out the cause of a Bad Pool Header error. If one of Windows drivers caused it, the tool would show you the name of the driver with the xxx.sys form.

You can easily find out which hardware it belongs to by pasting it into the www.carrona.org website. It’s a directory and will tell you the device name based on the .sys file.

After knowing the driver that caused the Bad Pool Header BSOD error, uninstall it and then download the latest version  from the manufacturer’s website and install it on your Windows PC.

If you’re using Windows 10, you only need to uninstall the driver, reboot the computer and then connect to the Internet. Your Windows OS will automatically scan for missing drivers, download the updated drivers and install them.

7. Restore Your Windows PC Back To Previous Working Point

If you tried all the methods above but the Bad Pool Header BSOD error persists, use the Windows System Restore feature to roll back your computer to a selected previous working point.

Technically, it’s a lightweight backup system, which helps to backup system files and creates points that allows users to roll back the computer to a specific point, in case something goes wrong.
