Blue Screen of Death Windows 10: Complete Troubleshooting Guide (BSOD Fix)

Understanding the Blue Screen of Death on Windows 10

A Blue Screen of Death (BSOD), formally known as a Stop Error, occurs when Windows 10 encounters a critical failure from which it cannot safely recover. The OS halts all processes, dumps memory to a file (typically located at C:\Windows\Minidump\), and reboots. Each BSOD displays a stop code — a hexadecimal or named code that identifies the failure category.

Common stop codes you will encounter include:

• IRQL_NOT_LESS_OR_EQUAL (0x0000000A) — A kernel-mode process or driver attempted to access a memory address at an improper IRQL (Interrupt Request Level). Almost always a driver bug.
• CRITICAL_PROCESS_DIED (0x000000EF) — A critical Windows process (such as csrss.exe, wininit.exe, or smss.exe) unexpectedly terminated.
• KERNEL_SECURITY_CHECK_FAILURE (0x00000139) — A kernel component violated a security check; often caused by incompatible or corrupt drivers.
• MEMORY_MANAGEMENT (0x0000001A) — Serious memory management error; often hardware RAM failure or corrupt page file.
• SYSTEM_SERVICE_EXCEPTION (0x0000003B) — An exception occurred while executing a system service routine; driver or system file corruption.
• UNEXPECTED_STORE_EXCEPTION (0x00000154) — Storage device (HDD/SSD) failure or driver issue with the storage stack.
• PAGE_FAULT_IN_NONPAGED_AREA (0x00000050) — System attempted to access a memory page that was not present; bad RAM or driver.

Step 1: Record the Stop Code and Find the Minidump

When a BSOD occurs, photograph or note the stop code displayed on the blue screen. Windows 10 shows it in plain English (e.g., "CRITICAL_PROCESS_DIED") along with a hex code.

After rebooting, open Event Viewer (eventvwr.msc) and navigate to: Windows Logs > System Filter by Event ID 41 (Kernel-Power, unexpected shutdown) and 1001 (BugCheck) to find BSOD logs.

Minidump files are stored at: C:\Windows\Minidump\

Use WinDbg (Windows Debugger from the Microsoft Store) or the free tool WhoCrashed to analyze .dmp files. WinDbg command to analyze a dump:

!analyze -v

Step 2: Boot into Safe Mode if You Cannot Reach the Desktop

If Windows keeps crashing at startup, access Windows Recovery Environment (WinRE):

1. Force-shutdown your PC 3 times during the boot logo to trigger Automatic Repair mode.
2. Go to: Troubleshoot > Advanced Options > Startup Settings > Restart
3. Press F4 for Safe Mode or F5 for Safe Mode with Networking.

Alternatively, boot from a Windows 10 installation USB and choose Repair your computer.

Step 3: Run System File Checker and DISM

Open Command Prompt as Administrator and run:

sfc /scannow

This scans and repairs protected Windows system files. If it reports that it "found corrupt files but was unable to fix some of them," escalate to DISM:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

After DISM completes, re-run sfc /scannow and reboot.

Step 4: Check and Update Drivers

Drivers are the #1 cause of BSODs. After a Windows Update, older drivers may become incompatible.

To identify the faulty driver:

• Open Device Manager (devmgmt.msc)
• Look for devices with a yellow warning icon
• Right-click > Properties > Driver tab

To roll back a driver:

• Right-click device > Properties > Driver tab > Roll Back Driver

For IRQL_NOT_LESS_OR_EQUAL and KERNEL_SECURITY_CHECK_FAILURE, the culprit is often:

• Network adapter drivers (especially Realtek, Killer Ethernet/WiFi)
• GPU drivers (NVIDIA/AMD)
• ASUS utility drivers (Armory Crate, AI Suite III)

Enable Driver Verifier (advanced) to catch misbehaving drivers:

verifier /standard /all

Warning: This will cause deliberate BSODs to identify the bad driver. Disable after testing:

verifier /reset

Step 5: Run Windows Memory Diagnostic for MEMORY_MANAGEMENT Errors

Press Win + R, type mdsched.exe, and press Enter. Choose Restart now and check for problems.

For deeper testing, download and run MemTest86 from a bootable USB — run at least 2 full passes (each pass takes 30-60+ minutes). Any errors indicate failing RAM. Try:

1. Reseating RAM sticks (remove and firmly re-insert)
2. Testing one stick at a time
3. Replacing faulty sticks

Step 6: Check Storage Drives for UNEXPECTED_STORE_EXCEPTION

Run CHKDSK on your system drive:

chkdsk C: /f /r /x

Schedule it for next reboot if the drive is in use. Also check drive health with:

wmic diskdrive get status

or use CrystalDiskInfo (free tool) to read S.M.A.R.T. data.

Step 7: Uninstall Problematic Windows Updates

If BSODs started after a Windows Update:

1. Go to Settings > Update & Security > Windows Update > View Update History > Uninstall Updates
2. Or use CMD:

wusa /uninstall /kb:XXXXXXXXX

(Replace XXXXXXXXX with the KB number from Update History)

3. To pause future updates temporarily:

reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" /v NoAutoUpdate /t REG_DWORD /d 1 /f

Step 8: ASUS-Specific BSOD Fixes

ASUS systems running Armory Crate, AI Suite III, or GPU Tweak are prone to BSODs due to aggressive system-level access by these utilities.

1. Uninstall Armory Crate via Settings > Apps
2. Also remove the Armory Crate Service using the official ASUS Armoury Crate Uninstall Tool
3. Update BIOS/UEFI from the ASUS support website for your specific model
4. Update chipset drivers from AMD or Intel's official websites (not Windows Update)
5. Update Realtek Audio/LAN drivers directly from ASUS support page

Step 9: Perform a Clean Boot to Isolate Software

msconfig

Go to the Services tab, check Hide all Microsoft services, then click Disable all. Go to the Startup tab and open Task Manager to disable all startup items. Reboot. If BSODs stop, re-enable services in batches to isolate the culprit.

Step 10: Last Resort — Reset Windows 10

If nothing works:

1. Settings > Update & Security > Recovery > Reset this PC
2. Choose Keep my files (reinstalls Windows, removes apps/drivers) or Remove everything (full clean install)

Alternatively, perform a clean install using the Windows 10 Media Creation Tool from Microsoft.
