The BAD POOL CALLER blue screen error can be a frustrating experience for Windows 11 users. This error typically occurs when your system encounters a critical issue that prevents normal operation. Common culprits include hardware incompatibilities, aggressive overclocking, outdated drivers, or problematic third-party software. Let’s explore several methods to resolve this error, starting with the most effective solutions.
Method 1: Update Your Drivers
Outdated or corrupted drivers are often the root cause of the BAD POOL CALLER error. Here’s how to update them:
- Access the Device Manager by right-clicking the Start button and selecting it from the menu.
- Expand a hardware category to view its associated drivers.
- Right-click on a driver and choose “Update driver.”
- Select “Search automatically for drivers” to let Windows find and install the latest version.
- Repeat this process for all important drivers, especially those related to your graphics card, network adapters, and storage controllers.
Method 2: Remove Problematic Applications
Sometimes, recently installed software can conflict with your system, triggering the BAD POOL CALLER error. To uninstall suspicious applications:
- Open the Settings app using the Windows key + I shortcut, then navigate to “Apps.”
- Click on “Installed apps” at the top of the page.
- Locate the app you suspect is causing issues, click the three dots next to it, and select “Uninstall.”
Method 3: Run System File Checker and DISM
Windows includes built-in tools to repair system files that might be causing the BAD POOL CALLER error:
- Open Command Prompt as administrator by searching for “cmd” in the Start menu and selecting “Run as administrator.”

Method 4: Perform a Memory Diagnostic
Faulty RAM can lead to the BAD POOL CALLER error. Use Windows Memory Diagnostic to check for issues:
- Search for “memory” in the Start menu and select “Windows Memory Diagnostic.”

Method 5: Stop Overclocking
If you’ve overclocked your CPU or GPU, revert to default settings as overclocking can sometimes lead to system instability and the BAD POOL CALLER error.

Method 9: Reset Your PC
As a last resort, you may need to reset Windows:
