Fixing 0x00000004 INVALID_DATA_ACCESS_TRAP Stop Code on Windows 10 & 11 – Step by Step

Short Answer

The 0x00000004 INVALID_DATA_ACCESS_TRAP stop code, commonly known as a Blue Screen of Death (BSOD), occurs when Windows detects an invalid memory access attempt. This can happen due to hardware issues, corrupted system files, or problematic drivers. While frustrating, this error is often fixable with simple troubleshooting steps.

Overview

The 0x00000004 INVALID_DATA_ACCESS_TRAP BSOD indicates that Windows attempted to access memory in a way that was not allowed, leading to a system crash. This stop code is one of the most common BSOD errors and can appear during normal operation or when specific tasks are running.

Common Causes

The 0x00000004 BSOD is typically caused by one of the following issues:

• Faulty hardware: Problems with RAM, hard drives, or other memory-related components.
• Corrupted system files: Critical Windows files may be missing or damaged.
• Outdated or incompatible drivers: Drivers that are not properly updated can trigger this error.
• Malware or viruses: Malicious software can corrupt memory or system processes.
• Overheating or power issues: If your system overheats or experiences unstable power, it may cause memory errors.
• Software conflicts: Conflicts between applications or Windows updates can lead to this stop code.

Fix Methods

Below are step-by-step solutions to resolve the 0x00000004 INVALID_DATA_ACCESS_TRAP BSOD. Start with the simplest methods and proceed if the issue persists.

1. Restart Your Computer

The most basic fix is to restart your computer. Sometimes, a temporary glitch or memory conflict can cause this error, and a simple reboot may resolve it without further intervention.

2. Check for Hardware Issues

Faulty hardware, particularly RAM or storage devices, is a frequent culprit behind this BSOD. Follow these steps to diagnose potential hardware problems:

• Run the built-in Windows Memory Diagnostic tool by pressing Win + R, typing mdsched, and selecting “Restart now and check for problems.” This will scan your RAM for errors.
• If the error persists, test your hard drive using the Command Prompt. Open it as an administrator and run:

  chkdsk /f /r

  Press Enter, then confirm if prompted to schedule the scan on the next reboot.

• Check for loose connections, especially in your RAM slots or storage drives. Ensure all components are securely seated.
• If you have multiple RAM sticks, try running your system with one stick at a time to see if the error occurs with a specific module.

3. Update Your Drivers

Outdated or incompatible drivers can trigger memory access errors. To update them:

• Press Win + X and select “Device Manager.” This will open a list of all installed hardware components.
• Expand categories like “Display adapters,” “Sound, video & game controllers,” or “System devices” to locate outdated drivers.
• Right-click on any driver with a yellow exclamation mark and select “Update driver.” Choose the option to search automatically for updated drivers.

4. Run System File Checker (SFC) and DISM

• • Open Command Prompt as an administrator by pressing Win + X and selecting “Terminal (Admin).”
  • Run the System File Checker tool with:

    sfc /scannow

    Wait for the scan to complete. If issues are found, Windows will attempt to repair them automatically.

DISM /Online /Cleanup-Image /RestoreHealth

This may take longer but can fix deeper corruption.

5. Scan for Malware

Malware can corrupt system files or memory, leading to this BSOD. Run a full system scan using Windows Defender:

• Open Windows Security by clicking the shield icon in your taskbar.
• Go to “Virus & threat protection” and click “Quick Scan.” If no threats are found, proceed with a “Full Scan.”
• Follow any additional steps if malware is detected, such as quarantining or removing it.

6. Test for Overheating

• Use third-party tools like HWMonitor or Core Temp to check CPU, GPU, and storage temperatures.
• If overheating is detected, clean your fans and vents or reapply thermal paste if necessary.
• Ensure your computer has proper airflow and is not running in an enclosed space.

7. Check for Windows Updates

Outdated Windows components may cause conflicts leading to this error. Install the latest updates:

• Press Win + I to open Settings, then go to “Update & Security.”
• Click “Check for updates” and install any pending updates.
• Restart your computer after applying the updates to ensure changes take effect.

8. Disable or Remove Problematic Software

If the BSOD appears after installing new software, it may be causing a conflict. To troubleshoot:

• Boot into Safe Mode by holding Shift while clicking “Restart” in the Start menu.
• Uninstall recently installed applications or drivers from “Settings > Apps > Installed apps.”
• If the issue persists, disable startup programs to see if a specific application is responsible. Press Ctrl + Shift + Esc, go to the “Startup” tab in Task Manager, and disable non-essential items one by one.

9. Test RAM with Third-Party Tools

• Download the tool from its official website and create a bootable USB.
• Boot your computer using the USB and run multiple passes to check for memory errors.
• If errors are found, replace or reseat your RAM modules.

10. Check Event Viewer for Clues

The Event Viewer can provide additional details about what triggered the BSOD:

• Press Win + X and select “Event Viewer.”
• Navigate to “Windows Logs > System” in the left panel.
• Look for entries with critical errors around the time of the BSOD. These may indicate which driver or process caused the issue.
