• Viruses or malware: interference with normal operation or modification of system files
• Power and BIOS issues: overclocking failures and voltage instability

Common Windows 11 Blue Screen Stop Codes

Windows usually displays a stop code on the blue screen to help identify the possible cause. Although a stop code does not always provide the exact solution, it can provide important clues for troubleshooting.

Below are some common Windows 11 BSOD stop codes and their possible causes.

Quick Fixes for Windows 11 Blue Screen Error

Before trying advanced troubleshooting methods, you can start with some basic fixes that may resolve temporary system conflicts.

Fix 1: Restart Your Computer

A blue screen (BSOD) indicates that a fatal error has occurred in the core of the system and that it cannot continue to run stably. Restarting is a straightforward method to reinitialize the system.

Fix 2: Disconnect Unnecessary Devices

Fix 4: Boot Windows 11 into Safe Mode

If Windows 11 keeps showing a blue screen and you cannot access the desktop normally, try booting into Safe Mode. Safe Mode starts Windows with only basic drivers and services. So, you can access your system and troubleshoot the Windows 11 blue screen error.

Step 1: Restart the computer 2 or 3 times

Turn on your computer, and then long-press the Power button to shut down. Repeat this process 2 to 3 times, and the system will automatically enter Windows Recovery Environment (WinRE).

Step 2: Enter Safe Mode

On the Choose an option screen, click Troubleshoot > Advanced options > Startup Settings, and then click Restart. Press F5 to enter Safe Mode with networking.

After successfully entering Safe Mode, you can back up your files and carry out some advanced fixes.

Fix 5: Run Windows Memory Diagnostic Tool

Running the Windows Memory Diagnostic tool can detect whether there are problems with your computer’s memory (RAM).

Step 1: Open Windows Memory Diagnostics

Press the Win + R keys to open the Run dialog box, enter mdsched.exe, and press Enter.

Step 2: Select the restart option

You will see a prompt window. If you want to check immediately, select Restart now and check for problems (recommended). If you want to check later, select Check for problems at the next time I start my computer.

Step 3: The system will restart and automatically detect memory

The diagnosis process may take several minutes. After the detection is completed, the system will automatically restart and return to Windows.

Step 4: View the test results

After logging into the system, press the Win + X keys and select Event Viewer. Select Windows Log > System, click Filter Current Log on the right, and then select MemoryDiagnostics-Results. The log will show whether memory errors are found.

If errors are found, consider replacing the RAM to prevent system instability.

How to Recover Data When Windows 11 Cannot Boot Due to BSOD

A continuous BSOD loop may prevent you from accessing important files stored on the computer. Before performing major repairs or reinstalling Windows, it is recommended to recover your important data to avoid potential data loss.

MiniTool Power Data Recovery is a data recovery tool that supports extracting data from damaged or inaccessible Windows systems.

When Windows cannot boot, this software allows you to create a bootable disk (usually a USB drive). You can then boot the computer from this disk and access the drives in the original system for data recovery.

It is compatible with multiple file systems, including NTFS, FAT32, exFAT, and Ext2/3/4. And, it supports recovering documents, pictures, videos, and so on.

Note that the free edition does not support this.
