Things to know

  • Sometimes the BAD POOL CALLER occurs due to issues with certain modems, such as those from Huawei, when they are used as network adapters instead of modems. You can use the modem software to set it to work as a modem only.
  • Hardware problems can also cause the error, in which case you will need to check your hardware. You can open your CPU case and see that components like the RAM are installed properly, and even remove and reseat them.
  • If you've connected a lot of peripherals, such as USB devices, external displays, printers, etc., disconnecting them can also help fix the problem if it was caused by one of the connected devices.
  • You can also navigate to the C:\Windows\Minidump folder and check whether Windows is creating any dump files. If it is, you can analyze the files to identify the cause of the error or get someone with the required technical knowledge to take a look at them and help you out.
  • While missing out on important updates can cause problems, sometimes updates can be buggy and may cause issues themselves. So, consider uninstalling recent updates from the Updates page in Windows Settings as a possible solution to the BAD POOL CALLER BSOD error.
  • If you're stuck on the BSOD and cannot access Advanced Options or Safe Mode, you will need the Windows Installation Media to boot into the OS. You can also use your Recovery Drive for this purpose if you had set it up earlier. Once inside, choose the 'Repair your computer' option to access Advanced Options.
