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- Outdated or incompatible drivers (especially storage or disk-related)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
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
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.
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Outdated or conflicting drivers (especially storage or chipset) can cause this error.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.
- Press Win + R, type
- Use Windows Memory Diagnostic:
- 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.
