What is the 0x000000D7 Error?


The 0x000000D7 error, displayed with the message “Cannot nest calls to LoadModule”, occurs when a driver or kernel-mode process attempts to load executable modules recursively or in an invalid sequence. In Windows, module loading is tightly controlled by the kernel to maintain system integrity. When a driver or low-level process improperly invokes LoadModule, especially while another module load operation is already in progress, Windows detects this unsafe behavior and triggers a Blue Screen of Death to prevent memory corruption or system instability. This error is commonly linked to faulty or incompatible drivers, corrupted system components, improper driver initialization logic, or conflicts with kernel-level software.

Causes

  • Faulty or incompatible drivers attempting improper or nested module loading.
  • Driver bugs causing recursive calls to LoadModule.
  • Corrupted system files affecting module and process management.
  • Conflicts with third-party kernel-level software such as antivirus tools, VPNs, virtualization platforms, or debugging utilities.
  • Improper driver initialization during system startup.
  • Outdated BIOS or firmware causing low-level execution conflicts.

Resolution Steps




1. Disable Driver Verifier (If Enabled)

  • Boot into Safe Mode.
  • Open Command Prompt as Administrator.
  • Run:verifier /reset
  • Restart the system to disable Driver Verifier.

2. Update or Roll Back Drivers

  • Open Device Manager.
  • Update outdated drivers using official manufacturer sources only.
  • Roll back recently installed drivers if the BSOD began after a driver update.
  • Focus on chipset, storage, graphics, and network drivers.

3. Repair Corrupted System Files

  • Open Command Prompt as Administrator.
  • Run:sfc /scannow
  • After completion, run:DISM /Online /Cleanup-Image /RestoreHealth
  • Restart the system once both scans complete.

4. Uninstall Conflicting Third-Party Software

  • Boot into Safe Mode.
  • Uninstall recently installed kernel-level software such as antivirus programs,
  • VPN clients, virtualization tools, debugging software, or system monitors.
  • Restart the system normally and check for stability.

5. Check Disk and File System Integrity

  • Open Command Prompt as Administrator.
  • Run:chkdsk C: /f /r /x
  • Restart and allow the disk scan to complete.

6. Test RAM for Memory Issues

  • Open the Run dialog.
  •  Run:mdsched.exe
  • Restart and allow Windows Memory Diagnostic to complete.
  • Test RAM modules individually if errors are found and replace faulty hardware if required.

7. Reset BIOS / UEFI Settings

  • Enter BIOS or UEFI during system startup.
  • Select Load Optimized Defaults.
  • Disable CPU, GPU, and RAM overclocking.
  • Save changes and exit.

8. Perform a Clean Boot

  • Press Windows + R.
  • Run:msconfig
  • Hide all Microsoft services and disable remaining services.
  • Open Task Manager and disable all startup applications.
  • Restart and observe system behavior.

9. Install Latest Windows Updates and Firmware

  • Open Windows Update.
  • Install all available updates, including optional driver updates.
  • Update motherboard BIOS or UEFI firmware to the latest stable version.

10. Perform an In-Place Upgrade or Clean Install

  • Use the Windows Installation Media Tool.
  •  Choose Upgrade this PC now to repair Windows without data loss.
  • If the BSOD persists, back up critical data and perform a clean installation.

The 0x000000D7 BSOD is typically caused by improper driver behavior, recursive module loading, corrupted system files, or conflicts with kernel-level software.

To resolve this error effectively:

  • Disable Driver Verifier if enabled.
  • Update or roll back problematic drivers.
  • Repair system files using SFC and DISM.
  • Remove conflicting kernel-level utilities.
  • Reset BIOS or UEFI settings and keep Windows updated.

If the issue persists, an in-place repair or clean installation offers a permanent solution. Maintaining stable drivers, clean system files, and updated firmware helps prevent the 0x000000D7 BSOD and ensures long-term Windows reliability.
