The BAD POOL CALLER error is a critical Blue Screen of Death (BSOD) issue that occurs in Windows 11, often linked to memory management and faulty drivers. This error indicates that a process or driver attempted to perform an illegal operation on a memory pool, leading to system instability.
Common triggers include outdated or incompatible drivers, corrupted system files, or faulty hardware. The error code 0x000000C2 is typically associated with this issue. Addressing it requires a systematic approach, including driver updates, memory diagnostics, and system configuration adjustments.
Step 1: Update or Roll Back Drivers
Outdated or incompatible drivers are a leading cause of the BAD POOL CALLER error. To resolve this, ensure all drivers, especially those for critical components like graphics cards and network adapters, are up to date. Use the Device Manager to check for updates or visit the manufacturer’s website for the latest versions.
If the error started after a recent driver update, rolling back to a previous version may help. Navigate to Device Manager, right-click the problematic driver, and select ‘Properties.’ Under the ‘Driver’ tab, choose ‘Roll Back Driver’ if available. This can restore stability if the new driver is incompatible with your system.
Step 2: Run Memory Diagnostics
Faulty RAM can also trigger the BAD POOL CALLER error. Windows 11 includes a built-in Memory Diagnostic Tool to identify memory-related issues. To use it, press ‘Windows + R,’ type ‘mdsched.exe,’ and press Enter. Choose ‘Restart now and check for problems’ to initiate the scan.
If the tool detects errors, consider replacing the faulty RAM module. For laptops or systems with soldered RAM, professional repair may be necessary. Regularly running memory diagnostics can prevent future BSOD errors and ensure system stability.
Step 3: Check for Corrupted System Files
Corrupted system files can lead to the BAD POOL CALLER error. Windows 11 provides tools like System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) to repair these files. Open Command Prompt as an administrator and run ‘sfc /scannow’ to scan and fix corrupted files.
If SFC doesn’t resolve the issue, use DISM to repair the Windows image. Run ‘DISM /Online /Cleanup-Image /RestoreHealth’ in Command Prompt. This process may take some time but can effectively restore system integrity and eliminate BSOD errors.
Step 4: Adjust Virtual Memory Settings
Incorrect virtual memory settings can contribute to memory management issues. To adjust these settings, right-click ‘This PC,’ select ‘Properties,’ and click ‘Advanced system settings.’ Under the ‘Advanced’ tab, click ‘Settings’ in the Performance section, then navigate to the ‘Advanced’ tab again and click ‘Change’ under Virtual Memory.
Ensure ‘Automatically manage paging file size for all drives’ is checked. If unchecked, manually set the paging file size to a recommended value. This can help prevent memory-related errors and improve system performance.
Step 5: Perform a Clean Boot
A clean boot can help identify third-party software conflicts causing the BAD POOL CALLER error. Press ‘Windows + R,’ type ‘msconfig,’ and press Enter. In the System Configuration window, select ‘Selective startup’ and uncheck ‘Load startup items.’ Restart your computer to boot with minimal drivers and programs.
If the error doesn’t occur during the clean boot, enable startup items one by one to identify the culprit. This method is particularly useful for isolating software conflicts and ensuring system stability.
Step 6: Update Windows 11
Microsoft regularly releases updates to address known issues, including BSOD errors. Ensure your system is running the latest version of Windows 11. Navigate to ‘Settings > Windows Update’ and click ‘Check for updates.’ Install any available updates and restart your computer.
If the error persists, consider joining the Windows Insider Program to access beta updates that may include fixes for unresolved issues. Keeping your system updated is crucial for maintaining stability and security.
