But just like with any other BSOD, you can take a shot at resolving BAD_POOL_CALLER by applying the fixes below. Should the error occur frequently, try working through them after booting Windows 10 in Safe Mode.
Reinstall Device Drivers
Reinstall Device Drivers
It’s best to kick things off by analyzing the BSOD dump files on your PC using WinDbg or NirSoft BlueScreenView. If a corrupt device driver is what’s behind the BAD_POOL_CALLER BSOD, that should help you nail it down quickly. You can then re-install the problematic driver with the steps that follow.
Update Device Drivers
Update Device Drivers
If reinstalling a faulty device driver didn’t help, try updating it. You can do that by downloading the latest drivers from the device manufacturer’s website. Or you can instead use a driver updater tool such as Driver Booster to get everything on your computer automatically up-to-date.
Roll Back Drivers
Roll Back Drivers
If the BAD_POOL_CALLER BSOD started popping up after updating the driver for a specific device, you must try rolling it back immediately. That should resolve any issues stemming from a broken or incompatible driver release.
Update the Operating System
Update the Operating System
Windows 10 updates help resolve BSOD-related issues by improving the stability of the operating system. If you have a habit of skipping updates, it’s best to take the time to install them now.
Uninstall Windows Updates
Uninstall Windows Updates
Windows 10 updates come with numerous bug fixes and performance enhancements. But they might also end up introducing issues. So if the BAD_POOL_CALLER BSOD occurred right after installing an operating system update, you must roll it back to its previous version.
Run the System File Checker
Run the System File Checker
Running an SFC (System File Checker) scan helps fix file corruption within the operating system. To do that, right-click the Start button and select Windows PowerShell (Admin). Follow that by running the following command: sfc /scannow After running an SFC scan, you might also want to run the Deployment Image Servicing and Management (DISM) tool. That helps fix stability-related problems in Windows 10.
Run the CHKDSK Utility
Run the CHKDSK Utility
Drive-related errors can also result in the BAD_POOL_CALLER BSOD. Try using the CHKDSK (Check Disk) utility to determine if that’s the case.
Run CHKDSK Utility at Startup
Run CHKDSK Utility at Startup
Running the CHKDSK utility at startup can help fix additional drive-related errors. Start by running the following command in an elevated Windows PowerShell console: chkdsk c: /r You must then confirm that you want the CHKDSK utility to scan your system drive for errors the next time you restart Windows 10. Press Y > Enter to do that.
Roll Back Your Computer
Roll Back Your Computer
Recent changes to the operating system (such as newer Windows updates and third-party program installations) can create conflicts and result in BSOD errors. But if you have System Restore active on your computer, you can try rolling back Windows 10 to an earlier state when everything worked perfectly.
Scan for Memory-Related Issues
Scan for Memory-Related Issues
Memory-related issues can also result in the BAD_POOL_CALLER BSOD on Windows. Try using the built-in Windows Memory Diagnostic tool or a third-party utility such as MemTest86 to check for memory-related errors. If the results indicate problems with the memory, you must replace the physical RAM modules on your PC.
Reset PC
Reset PC
Resetting Windows 10 to factory settings erases all data (except for any personal files), but that also helps the operating system start all over from a blank slate. So if none of the fixes above helped stop the BAD_POOL_CALLER BSOD, you must give that a shot. Should you want to go ahead, open the Start menu and select Settings > Update & Security > Recovery > Get started. Follow that by selecting Keep my files to reset your PC while retaining personal files, or Remove everything to revert everything to factory defaults. For more details, learn how resetting Windows 10 works.
What Else Can You Do?
What Else Can You Do?
If you had trouble running through the fixes above normally or in Windows 10’s Safe Mode, we recommend entering the Windows Recovery Environment (WinRE). It provides several tools that you can use to run startup repairs, fix disk-related errors, remove Windows updates, and so on. Furthermore, you might want to consider updating the BIOS or UEFI or reinstalling Windows 10 from scratch as a final measure to fixing the BAD_POOL_CALLER BSOD. But suppose you continue to have issues despite doing everything. In that case, you must contact a PC repair service to run additional diagnostics on your computer and replace any faulty internal hardware components.
