Facing a Blue Screen of Death (BSOD) on your Windows 11 PC can be frustrating. Not only does your computer abruptly shut down, but it also leaves you wondering what caused the crash and how to fix it. Don’t worry — this guide will walk you through practical steps to diagnose and resolve BSOD errors so you can get back to work or play smoothly and safely.
What is a Blue Screen of Death (BSOD)?
The BSOD, also called a stop error, is a critical system error in Windows that forces your computer to stop running to prevent damage. When it happens, Windows displays a blue screen with an error message or code, such as “CRITICAL_PROCESS_DIED” or “MEMORY_MANAGEMENT”. These errors can be caused by hardware failures, driver issues, or software conflicts.
Step-by-Step Guide to Fix BSOD Errors in Windows 11
1. Note the Specific Error Code
When the BSOD shows up, write down the error code and message. This info is essential for troubleshooting. For example, “PAGE_FAULT_IN_NONPAGED_AREA” typically points to faulty memory, while “IRQL_NOT_LESS_OR_EQUAL” often relates to driver problems.
2. Restart Your PC
Sometimes, a simple reboot can solve temporary glitches causing the BSOD. After restarting, see if the issue reoccurs.
3. Run Windows Memory Diagnostic
Faulty RAM often triggers BSODs, so testing your memory is a good early step.
- Press Windows + R, type
mdsched.exeand hit Enter. - Choose Restart now and check for problems.
- Your PC will reboot and scan your memory. If errors are found, consider replacing your RAM.
4. Update Windows 11 and Drivers
Outdated system files and drivers can cause incompatibilities leading to BSODs. To update:
- Go to Settings > Windows Update, click Check for updates, and install all available ones.
- Open Device Manager (
Windows + X > Device Manager), right-click devices (especially display adapters, network adapters), and select Update driver.
5. Uninstall Recently Installed Software or Drivers
If the BSOD started after installing new software or drivers, remove them:
- Go to Settings > Apps > Installed apps, find the software, and uninstall it.
- For drivers, use Device Manager to roll back or uninstall.
6. Run System File Checker and DISM
Corrupted system files can cause BSODs. Running repair tools often fixes this.
-
Open Command Prompt as administrator.
-
Type:
sfc /scannowand press Enter. Wait until the scan finishes. -
Next, run:
DISM /Online /Cleanup-Image /RestoreHealth
-
Restart your PC and check if BSODs persist.
7. Check Hard Drive Health
A failing hard drive might cause critical system errors.
- Open Command Prompt as admin.
- Run
chkdsk /f /rand press Enter. - You’ll be asked to schedule it for next reboot—agree and then restart your PC.
8. Use Safe Mode to Troubleshoot
Safe Mode loads Windows with minimal drivers and can help isolate the cause.
- Hold Shift and click Restart from the Start menu.
- Navigate: Troubleshoot > Advanced options > Startup Settings > Restart.
- After reboot, press 4 to enter Safe Mode.
- From here, uninstall suspect apps or use System Restore.
9. Perform System Restore
If you created restore points before the BSOD issue started, reverting can help.
- Search Create a restore point, open it.
- Click System Restore, follow the wizard, and choose a restore point before the error began.
10. Reset or Reinstall Windows 11
If all else fails, resetting Windows can solve stubborn BSOD problems.
- Go to Settings > System > Recovery.
- Click Reset PC and choose between Keep my files or Remove everything.
- Follow prompts to reinstall Windows.
Tips to Prevent BSOD in the Future
- Keep Windows and your drivers updated regularly.
- Avoid installing unverified software.
- Scan your PC for malware.
- Backup your important files.
- Regularly check hardware health, especially RAM and disk drives.
When to Seek Professional Help
If you try all these steps and BSOD errors continue, it’s time to ask a professional. Persistent stop errors might indicate deeper hardware issues like a failing motherboard, power supply problems, or damaged storage devices that call for expert diagnostics.
