What is BSOD?

The Blue Screen of Death (BSOD), also known as a Stop error, Blue Screen, or fatal error, is a critical error displayed by Windows in the event of a fatal system error that your Windows is not able to handle or resolve automatically.

When the blue screen flashes and shows such an error message on your blue screen, "Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you." then it restarts automatically, you need to disable the 'automatic restart on system failure' setting.

Here are some common error messages:

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
IRQL_NOT_LESS_OR_EQUAL
PAGE_FAULT_IN_NONPAGED_AREA
SYSTEM_SERVICE_EXCEPTION
BAD_SYSTEM_CONFIG_INFO
CRTICAL_PROCESS_DIED
KERNEL_DATA_INPAGE_ERROR

So what causes the Blue Screen of Death? The reasons are on the list.

Insufficient space in the system disk
Faulty device drivers
BIOS misconfiguration
Damaged hard disk
Outdated Windows operating system
Incorrect entries in the system's registry
Incompatibility between the old program and the security software

How to fix Blue Screen of Death on Windows 7/8/10/11?

Newer versions of Windows, like 10 or 11, are more stable than earlier versions, so it seems like you hopefully run into BSOD from time to time. It doesn't matter if the Blue Screen of Death appears one time and the issue will be fixed automatically after you restart. But if it occurs frequently on your Windows, you can take the ways following.

Check for recent changes

The most important step to fix this issue you can take is to check what you did just before your Windows stopped working. Many times, you'll start seeing blue screen errors after making a change to your system.

Therefore, you can undo the change you made and restart your computer to check whether the issue has been fixed. Depending on the different changes you do, you need to take different actions to undo the change.

Last Known Good Configuration:

The Last Known Good Configuration is a shortcut to solve the blue screen of death on Windows. Generally, it can solve most abnormalities, but it is not working if your PC cannot be started.

Restart your Windows and long press F8 into Safe Mode.
Select The Last Known Good Configuration and press Enter.

System Restore:

System Restore in Windows allows you to return your system to a previous state. It's a handy troubleshooting tool, as it's simple to use and lets you see if your issue is software-based.

Start your PC and click Repair your computer at the left bottom of the screen.

Check and update device drivers

As we mentioned above, BSOD may be caused by outdated device drives, thus, you need to check your device drivers. If the device drivers are outdated or corrupted, you can update or reinstall them.

Press Win + X to choose Device Manager in the power user menu.
Check if there's any yellow triangle icon under the device driver.
Right-click the problematic drivers and then click Update driver.

Windows will install the driver on your PC automatically if there's an available driver. If Windows doesn't reinstall your driver, you need to go to your driver manufacturer's website to download the latest driver of your device.

Run SFC Scan

One of the reasons why the Blue Screen of Death occurs on your Windows 7/8/10/11 is corrupted files. Therefore, you can use Command Prompt to run SFC Scan to check for damaged Windows system files and attempts to fix them.

Click the search icon in the taskbar and type in Command Prompt in the search box.
Right-click Command Prompt and choose Run as administrator.
Type in the below command and press Enter to run.
sfc/scannow

Wait for the process to finish and make sure you don't close the Command Prompt window or shut down your PC during the process. After finished, it will fix all the detected errors, including the corrupted system files.

Check for Windows

Except for the corrupted system files, malware and damaged hardware are also the main reasons that cause this issue. Malware will damage your Windows system files, resulting in a blue screen. So you should run a scan for malware to get rid of anything like this.

Besides, checking for your hardware is an important part as well. If you haven't figured out what causes a blue screen of death, you can check your computer components. Sometimes a failing stick of RAM, or another bad component, can result in a blue screen.

Reinstall Windows

If all the above ways are failed, you need to reinstall Windows on your PC. If you're sure there's nothing wrong with your drivers, hardware, malware, and system file issues, there must be some potential problems in your system.
