What is 0x00000041 Error?


The Windows Stop Code 0x00000041, labelled MUST_SUCCEED_POOL_EMPTY, is a Blue Screen of Death (BSOD) that occurs when the operating system tries to allocate critical memory pool space but none is available. This typically occurs during system shutdown or startup and indicates resource leaks or shutdown conflicts involving kernel-mode drivers or power management. This error is uncommon but may appear in systems with improper driver unloading behaviour, hardware compatibility issues, or faulty shutdown procedures.

Causes

  • Faulty or Misbehaving Drivers: Drivers that fail to release memory during shutdown may cause the system pool to be depleted.
  • Incomplete Driver Unloads: Kernel-mode drivers not unloading properly can leave behind active allocations.
  • Power Management Conflicts: Faulty ACPI configurations or BIOS bugs can prevent clean power-down sequences.
  • Abrupt Shutdowns or Forced Reboots: Improper shutdowns may leave the system in an inconsistent memory state.
  • Memory Leaks from Kernel Components: Drivers or services that leak memory into the must-succeed pool can trigger this issue.
  • BIOS or Firmware Incompatibility: An Outdated BIOS may not manage low-level shutdown operations correctly.

Resolution Steps




1. Update or Roll Back Drivers

  • Press Win + X → Select Device Manager
  • Focus on system-level drivers like storage, ACPI, chipset, and graphics
  • Right-click → Update Driver or select Roll Back Driver if available

2. Run System File Checker and DISM

  • Open Command Prompt (Admin), then run:
  • sfc /scannow
  • Once completed, run:
  • DISM /Online /Cleanup-Image /RestoreHealth
  • These tools fix system components that handle memory and power management

3. Check for Memory Leaks and Driver Issues

  • Open Event Viewer → Windows Logs → System
  • Look for critical errors or driver unload failures before shutdown
  • Uninstall or replace problematic drivers identified in logs

4. Update BIOS and Power Management Firmware

  • Visit your PC/motherboard manufacturer’s support page
  • Download and apply the latest BIOS and ACPI-compliant firmware
  • Ensure compatibility with Windows power management protocols

5. Disable Fast Startup

  • Go to Control Panel → Power Options → Choose what the power buttons do
  • Click “Change settings that are currently unavailable”
  • Uncheck “Turn on fast startup” and save changes
  • This ensures complete driver unloading during shutdown

6. Perform System Restore

If the issue started recently:

  • Control Panel → Recovery → Open System Restore
  • Choose a restore point before the first BSOD occurrence
  • Follow prompts to complete restoration

7. Test System RAM

  • Press Win + R → Type mdsched.exe → Enter
  • Choose “Restart now and check for problems”
  • Let the diagnostic complete and act on any issues detected
