Solution Steps
- 1 Boot into Safe Mode: Press Windows key + I, go to System → Recovery → Advanced startup, and click 'Restart now'. Then choose Troubleshoot → Advanced options → Startup Settings → Restart, and press 4 for Safe Mode. Safe Mode loads only essential drivers, so if the error doesn't occur, it's driver-related.
- 2 In Safe Mode, press Windows key + X and select 'Device Manager'. Look for devices with a yellow exclamation mark. Right-click and select 'Update driver' → 'Search automatically for drivers'. If that fails, uninstall the device and restart to let Windows reinstall it.
- 3 Run the System File Checker: press Windows key + R, type 'cmd', right-click and select 'Run as administrator'. Type 'sfc /scannow' and press Enter. This repairs corrupted system files that might be causing the bad pool request.
- 4 Check for Windows updates: Press Windows key + I, go to Windows Update, and click 'Check for updates'. Install all updates, as they often include driver fixes.
- 5 If the error persists, use the Windows Memory Diagnostic: press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. Faulty RAM can cause pool corruption.
- 6 Analyze the crash dump: Use the 'WinDbg' tool from the Microsoft Store or 'BlueScreenView' to open the minidump file in C:\Windows\Minidump. This will tell you which driver caused the error. Then, update or uninstall that specific driver.
