The “Bad Pool Caller” error is a common Blue Screen of Death (BSOD) issue that Windows 10 users encounter. This error indicates a problem with the system’s memory pool, which can occur due to incompatible drivers, corrupted system files, or hardware conflicts. Although the error can be alarming, it’s fixable with a few simple troubleshooting steps. Here are three effective ways to resolve the Bad Pool Caller error on Windows 10.

1. Update or Roll Back Drivers

Faulty or outdated device drivers are one of the most common causes of the Bad Pool Caller error. Updating or rolling back problematic drivers can resolve the issue.

Steps to update drivers:

1. Press Windows + X and select Device Manager.
2. Look for any devices with a yellow exclamation mark, indicating a driver issue.
3. Right-click on the problematic device and select Update Driver.
4. Choose Search automatically for updated driver software and let Windows update the driver.
5. Restart your computer to see if the error is resolved.

Steps to roll back drivers:

2. Go to the Driver tab and click Roll Back Driver (if the option is available).
3. Follow the on-screen instructions and restart your computer.

Tip: If you recently installed a new driver and started experiencing the error, rolling back the driver to a previous version can help.

2. Run Windows Memory Diagnostic

The Bad Pool Caller error can also stem from issues with your computer’s RAM. Running the Windows Memory Diagnostic tool can help identify and fix memory-related problems.

Steps to run the Windows Memory Diagnostic tool:

1. Press Windows + R to open the Run dialog box.
2. Type mdsched.exe and press Enter.
3. Choose Restart now and check for problems. Your computer will reboot, and the diagnostic tool will run automatically.
4. Wait for the process to complete. The system will restart again, and the results will display on your screen.

If the tool detects errors, you may need to replace your RAM or reseat it in the slots to resolve the issue.

3. Check and Repair Corrupted System Files

Corrupted system files can cause instability and lead to BSOD errors like Bad Pool Caller. Using built-in Windows tools like System File Checker (SFC) and Deployment Image Servicing and Management (DISM) can repair these files.

Steps to run SFC and DISM:

1. Press Windows + S and type Command Prompt.
2. Right-click on Command Prompt and select Run as administrator.
3. Type the following command and press Enter:
   bash

   Copy code

   sfc /scannow

4. Wait for the process to complete. If the tool finds and fixes issues, restart your computer.
5. If the problem persists, use DISM to repair the Windows image. Type the following commands one at a time, pressing Enter after each:
   mathematica

   Copy code

   DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
6. Once the process is complete, restart your computer.

These tools will scan and fix corrupted system files, which can often resolve the Bad Pool Caller error.

Conclusion

The Bad Pool Caller error on Windows 10 can be frustrating, but it is usually caused by issues with drivers, memory, or corrupted system files. By updating or rolling back drivers, running the Windows Memory Diagnostic tool, and repairing system files with SFC and DISM, you can resolve the error and get your system back to normal. If the problem persists, it might be worth considering a full system reset or seeking professional help to diagnose potential hardware failures.
