MULTIPLE IRP COMPLETE REQUESTS (0X00000040) Blue Screen Fix Guide (Windows 10/11)

The MULTIPLE IRP COMPLETE REQUESTS (0x00000040) blue screen error also known as a Stop Error or BSOD (Blue Screen of Death) occurs when Windows encounters an issue with how it processes input/output requests. This error can be frustrating but its often fixable with the right steps. Below well explain what causes this error and provide step-by-step solutions to resolve it.

What Causes the MULTIPLE IRP COMPLETE REQUESTS (0x00000040) Error?

The 0x00000040 BSOD typically happens when Windows fails to properly complete an I/O request often due to:

  • Corrupt system files or drivers
  • Faulty hardware (e.g. RAM hard drive or SSD)
  • Outdated or incompatible drivers (especially storage or disk-related)
  • Malware or virus infections affecting system stability
  • Improper shutdowns or sudden power loss during updates

How to Fix MULTIPLE IRP COMPLETE REQUESTS (0x00000040) Error

Method 1: Run System File Checker (SFC)

The sfc /scannow command repairs corrupted system files that may be causing the error. Follow these steps:

  • Open Command Prompt as Administrator:
    • Press Win + X then select Terminal (Admin) or Command Prompt (Admin).
  • Type the following command and press Enter:
    • sfc /scannow
  • The scan may take several minutes. Restart your PC afterward.

Method 2: Run DISM to Repair Windows Image

If SFC doesnt work use DISM to restore system files from a healthy backup:

  • Open Command Prompt as Administrator (as above).
  • Run these commands one by one pressing Enter after each:
    • DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
  • Wait for the process to finish then restart your PC.

Method 3: Check and Repair Disk Errors with CHKDSK

Corrupted disk sectors can trigger this error. Run CHKDSK to scan for issues:

  • Open Command Prompt as Administrator.
  • Type the following command (replace C with your system drive if needed):
    • chkdsk C: /f /r
    • /f: Fixes errors found.
    • /r: Locates bad sectors and recovers readable data.
  • If prompted schedule the scan for the next reboot or run it immediately (requires a restart).

Method 4: Update or Reinstall Problematic Drivers

Outdated or conflicting drivers (especially storage or chipset) can cause this error. Heres how to update them:

  • Press Win + X then select Device Manager.
  • Expand categories like Disk drives Storage controllers or Universal Serial Bus controllers.
  • Right-click each device select Update driver and choose Search automatically for drivers.
  • If the issue persists use Windows Update to check for updates.
  • For stubborn drivers download the latest version from the manufacturers website (e.g. Intel NVIDIA or your motherboard brand).

Method 5: Test and Replace Faulty Hardware

If hardware is failing (RAM SSD/HDD) it can trigger this error. Test with these steps:

  • Check RAM:
    • Use Windows Memory Diagnostic:
      • Press Win + R type mdsched.exe and press Enter.
      • Select Restart now and check for problems.
  • Test your storage drive:
    • Use third-party tools like CrystalDiskInfo to check for SMART errors.
    • If the drive is failing back up data and replace it immediately.

Method 6: Perform a Clean Boot to Isolate Software Conflicts

A clean boot starts Windows with minimal drivers/services helping identify if third-party software is causing the issue:

  • Press Win + R type msconfig and press Enter.
  • Go to the Services tab check Hide all Microsoft services then click Disable all.
  • Go to the Startup tab click Open Task Manager and disable all startup items.
  • Restart your PC. If no BSOD occurs re-enable services/apps one by one to find the culprit.

Method 7: Reset or Reinstall Windows (Last Resort)

If all else fails reset Windows while keeping files (guide here) or perform a clean install. Back up important data first.
