How to fix the Blue Screen of Death (BSOD) in Windows?
Blue Screen of Death (BSOD) is usually caused by hardware, driver or system file problems. You can troubleshoot and fix it through the following steps: 1. Check the recently installed hardware or driver, uninstall or roll back unstable devices; 2. Run sfc /scannow, DISM, chkdsk and other tools to scan system files and disk errors; 3. Use memory diagnostic tools to test memory failures; 4. Update the system and analyze the problem of positioning specific modules in the blue screen log. In most cases, it can be solved through gradual investigation.
Blue Screen of Death (BSOD) is one of the last pictures Windows users want to see. It usually means that the system has encountered a serious error and must be restarted to continue running. Although it looks scary, it can be troubleshooted and fixed in most cases. Below are some common reasons and corresponding solutions to help you quickly deal with the blue screen problem.

Check for recently installed hardware or drivers
Many blue screen problems are actually related to hardware or drivers. For example, if you just installed a new graphics card, memory stick, or updated the driver of a certain device, it may be incompatible.
Suggested practices:

- Remove the recently added hardware and see if it's still blue.
- Roll back or uninstall recently updated drivers, especially graphics cards, sound cards, and motherboard-related drivers.
- Use the "Backback Driver" feature in Device Manager to go back to the previous stable version.
- If you are not sure which driver has a problem, you can try to enter safe mode and check it one by one.
In this case, the blue screen code is usually INACCESSIBLE_BOOT_DEVICE
or DRIVER_IRQL_NOT_LESS_OR_EQUAL
, which can be further positioned according to the specific error code.
Scan system files and memory issues
System file corruption or memory failure is also a common cause of blue screen. Windows comes with some tools to help you check these problems.

Operation suggestions:
- Run
sfc /scannow
command to scan and repair the system files. - If this command doesn't find anything, try
DISM /Online /Cleanup-Image /RestoreHealth
to fix deeper system image problems. - Checking memory can be done using the Windows built-in "Windows Memory Diagnostics" tool, or it can be tested more thoroughly using MemTest86.
- If there is a problem with the hard disk, use
chkdsk /f /r
to check for disk errors.
These tools do not require additional downloads and can basically be run in a command prompt. If the system cannot be started, you can enter the recovery environment by installing the USB flash drive.
Update the system and view the blue screen log
Sometimes Microsoft has released patches for certain issues, but your system has not been updated yet. In addition, the log files generated during blue screen also contain key information.
You can do this:
- Make sure that the Windows system has been updated to the latest version.
- Use the "Event Viewer" to view the system logs, find the time point before and after the blue screen occurs, and see if there are any obvious abnormalities.
- Use WinDbg or BlueScreenView and other tools to analyze the .dmp file and find out the specific module that triggers the blue screen.
Pay attention to check the error name on the blue screen (such as PAGE_FAULT_IN_NONPAGED_AREA
) to lock the source of the problem faster with the analysis log.
Basically these commonly used methods. Don’t panic when encountering blue screens. Start with recent changes and gradually troubleshoot software and hardware problems. Most of the situations can be solved.
