Blue Screen of Death: How to Read the Stop Code and Fix It

A Blue Screen of Death (BSOD) is Windows telling you it hit a problem so serious it had to stop everything to prevent damage. That sounds frightening, but the stop code printed on the screen is actually a useful clue — not just a wall of text.

Step 1: Find the Stop Code

When the blue screen appears, look near the bottom for a line like STOP CODE: MEMORY_MANAGEMENT or a hex value like 0x0000001E. If your PC rebooted before you could read it, Windows saves the information in an event log.

1. Press Win + R, type eventvwr.msc, and press Enter.
2. Go to Windows Logs > System and look for events with level Critical or Error around the time of the crash.
3. Alternatively, open Settings > System > About and search for "Reliability Monitor" in the Start menu — it shows a timeline of crashes with the error code listed.

Step 2: Understand Common Stop Codes

• MEMORY_MANAGEMENT / 0x0000001A — Usually faulty or failing RAM. Run mdsched.exe (Windows Memory Diagnostic) to test your RAM overnight.
• DRIVER_IRQL_NOT_LESS_OR_EQUAL / 0x000000D1 — A driver tried to access memory it shouldn't. Often caused by a recently installed driver. Roll it back in Device Manager.
• CRITICAL_PROCESS_DIED / 0x000000EF — A core Windows process crashed. Run SFC and DISM (see below).
• NTFS_FILE_SYSTEM / 0x00000024 — File system corruption. Run chkdsk C: /f /r from an elevated Command Prompt.

Step 3: Run the Built-in Repair Tools

Open Command Prompt as administrator (right-click the Start button, choose Terminal (Admin)) and run these two commands in order:

sfc /scannow

Wait for it to finish, then run:

DISM /Online /Cleanup-Image /RestoreHealth

Both commands repair corrupted Windows system files and fix many BSODs on their own.

Step 4: Check for Driver and Windows Updates

Go to Settings > Windows Update and install any pending updates, including optional driver updates. Then open Device Manager, right-click any device with a yellow warning triangle, and choose Update driver.

Step 5: If It Keeps Happening

Frequent BSODs often point to failing hardware — RAM or a dying hard drive. Download and run your drive manufacturer's diagnostic tool to check drive health. If you added new hardware recently, remove it and see whether crashes stop.
