When encountering a BAD_POOL_CALLER blue screen error, it is usually caused by illegal access to the memory pool by the driver or system components. Solutions include: 1. Update or rollback the graphics card driver; 2. Uninstall third-party driver software or virtual machine tools; 3. Run sfc and DISM tools to repair system files; 4. Use memory diagnostic tools to check memory problems. Follow the steps to check one by one, and in most cases, the problem can be solved.

I encountered a BAD_POOL_CALLER blue screen error, usually because there was a problem with the system in memory management, especially when the driver or system components illegally accessed the memory pool. This problem occasionally occurs during Windows use, but don’t worry, we can troubleshoot and solve it step by step.

Below are some common and practical solutions to help you solve this blue screen error.

1. Update or rollback graphics card/hardware driver

In many cases, the BAD_POOL_CALLER error is caused by an outdated or damaged driver, especially graphics card drivers (such as NVIDIA, AMD, or Intel integrated graphics cards).

You can do this:

• Open Device Manager (right-click "Start Menu" → Device Manager)
• Expand "Show Adapter", right-click on your graphics card → Update Driver
• If it is already latest, you can try "rollback the driver" to the previous stable version to see if there is any improvement

In addition, you can also download the latest official drivers to install manually on the official website, instead of relying on the version that automatically updates Windows.

2. Check third-party driver software or virtual machine tools

Some third-party optimization software (such as some driver sprite tools) or virtual machine-related programs (such as VMware Tools, VirtualBox Guest Additions) may also cause such errors.

Recommended operations:

• Uninstall your recently installed driver optimization software
• If you are using a virtual machine, try uninstalling and reinstalling the corresponding tool (Tools/Additions)
• Or simply temporarily disable the virtual machine environment to test whether there will still be a blue screen

This type of software sometimes modify the underlying memory call method, and if it is incompatible with the system, problems will arise.

3. Run the system file checking tool

A corruption of Windows system files may also cause a BAD_POOL_CALLER error. It can be fixed with built-in sfc and DISM tools.

Execute the following command (run the command prompt as administrator):

• sfc /scannow
• DISM /Online /Cleanup-Image /RestoreHealth

These two commands are used to scan and repair system files and repair system images respectively. After running, restart the computer to see if the blue screen still appears.

4. Check if there is any problem with the memory

Although not the most common cause, problems with the memory stick themselves can also cause this error.

You can try:

• Using Windows Memory Diagnostic Tool (Windows Memory Diagnostic), you can find it by entering it in the search bar
• Or use MemTest86 to test if there are any bad blocks in the memory

If you find a memory exception, you can try changing the slot or changing the memory stick.

Basically these common solutions. Although BAD_POOL_CALLER seems scary, it is a problem with the driver or system files most of the time. You can usually solve it by following the above method. Remember to change only one setting at a time to facilitate confirmation of which step solved the problem.
