Fix BAD_POOL_CALLER Stop Error (0x000000C2) in Windows 8.1

PC Problems, Windows 8.1

Witnessing your Windows 8.1 system failing prey to yet another one of the Blue Screen of Death errors is anything but pleasant. Denoted by the value 0x000000C2 or simply 0xC2 , BAD_POOL_CALLER is a specific BSOD stop error that appears when a thread in the processor makes a bad pool request. This means that it is asking the system to use resources that are either unavailable, nonexistent, or simply under use by another thread. Upon failing to load the desired file, the PC runs into various errors and ultimately performs a reboot in an attempt to protect itself from any damage. However, the user is still left fetching the unsaved work, and cursing the computer along the way.

If you are encountering frequent system shutdowns owing to this fatal error, it is advised you do not overlook the gravity of this issue and immediately perform the troubleshooting steps listed in the section below.

Solutions

While sometimes, 0x000000C2 may be fixed by a simple reboot; in most cases it requires special diagnostic steps. This section looks deeper into these detailed methods and helps you resolve the matter in a correct and appropriate manner.

Analyze your Minidump file to find the root cause

As is the case for any BSOD error, 0xC2 saves an error report in the system drive (typically C) for future analysis. This .dmp file notes the corresponding processes that occurred during the crash, and allows the user to pinpoint the driver or application making the invalid call and thus ceasing the computer operations. That element can be either updated or reinstalled to fix the problem.

Note: To read minidump files, you will need to install a Debugging Tool, such as WinDbg available from Microsoft’s official website.

Here’s a simple guide to help you find and interpret .dmp files immediately after you recover from a PC crash:

  • Open Run box (Windows + R) and type %systemroot%. Enter to launch your Windows directory
  • Navigate to Minidump folder
  • Open the recent .dmp file and notice the error labeled as BAD_POOL_CALLER
  • Look for the flawed component listed under the Probably caused by wordings, or other similar sentence
  • Once identified, get the latest updates or reinstall the program to inhibit any further issues

Sometimes, users are not able to view the Minidump folder and thus fail to scrutinize BSODs. This can be fixed by configuring the computer appropriately to generate .dmp files and save them in the targeted path. Proceed with the steps illustrated:

  • Reach Windows directory from the Run box as described above
  • Look for Minidump folder. If not found, right-click anywhere in the explorer, hover over to the option New, and then choose Folder to create a new folder
  • Name the folder Minidump
  • Open System console by pressing Windows + Pause key. Click Advanced system settings from the left pane to open System Properties
  • View the Advanced tab and click Settings button displayed in the Performance box
  • Open Advanced view from the top and click Change button
  • Ensure the option Automatically manage paging file size for all drives is checked.
  • Click OK to close Performance Options box
  • Navigate to the System Properties again and choose Settings listed under Startup and Recovery
  • Under System failure, ensure check mark against Write an event to the system log.
  • In Write debugging information section and choose Small memory dump (128 KB) option
  • Also confirm the Dump file path is set to %systemroot%\Minidump
  • Click OK once done
