What is the 0x000000DA Error?


The 0x000000DA error occurs when a driver or kernel-mode process attempts to access memory that it does not have permission to use while operating at a high Interrupt Request Level (IRQL). At elevated IRQL levels, Windows restricts access to pageable memory to maintain system stability. If a driver violates these rules—by referencing invalid or pageable memory—Windows immediately halts execution and triggers a Blue Screen of Death (BSOD) to prevent system corruption. This error is commonly associated with faulty drivers, incompatible hardware, corrupted system files, or unstable system configurations.

Causes

  • Faulty or outdated device drivers
  • Drivers accessing invalid or pageable memory at high IRQL
  • Incompatible or newly installed hardware
  • Corrupted Windows system files
  • BIOS or firmware incompatibilities
  • Overclocking or unstable hardware configurations

Resolution Steps




1. Disable Driver Verifier (If Enabled)

  • Boot into Safe Mode.
  • Open Command Prompt (Administrator).
  • Run:verifier /reset
  • Restart the system.

2. Update or Roll Back Device Drivers

  • Open Device Manager.
  • Identify recently updated or problematic drivers.
  • Update drivers using official manufacturer sources only.

Roll back drivers if the issue started after a recent update.

3. Repair Corrupted System Files

  • Open Command Prompt (Administrator).
  • Run:sfc /scannow
  • After completion, run:DISM /Online /Cleanup-Image /RestoreHealth
  • Restart once both scans finish.

4. Uninstall Incompatible Hardware or Software

Boot into Safe Mode.

Uninstall recently added:

  • Device drivers
  • Kernel-level software
  • System utilities or tuning tools

Restart normally and check system stability.

5. Test System Memory (RAM)

  • Press Windows + R, type mdsched.exe, and press Enter.
  • Choose Restart now and check for problems.
  • Replace faulty RAM modules if errors are detected.

6. Reset BIOS / UEFI Settings

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

7. Check Disk and File System Integrity

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

8. Perform a Clean Boot

  • Press Windows + R, type 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/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 important data and perform a clean installation.

The 0x000000DA BSOD occurs when drivers or kernel processes improperly access memory at a high IRQL level, leading to system instability.

To resolve this error effectively:

  • Disable Driver Verifier if enabled
  • Update or roll back faulty drivers
  • Repair system files using SFC and DISM
  • Test memory and reset BIOS settings
  • Keep Windows and firmware up to date

If the issue continues, an in-place repair or clean installation provides a long-term solution. Maintaining stable drivers, compatible hardware, and updated system software helps prevent the 0x000000DA IRQL_NOT_LESS_OR_EQUAL error and ensures long-term Windows stability.
