I. Reasons for computer blue screen

The Blue Screen of Death (BSoD) is a stop error display in Windows that signals system conflicts and crashes. During a BSoD, Windows may freeze or automatically restart. Modern Windows versions manage errors more effectively, significantly reducing the incidence of blue screens compared to the past.

Causes of blue screen errors:
A blue screen error typically displays a code indicating the cause, which can guide users to a solution. Often, Windows self-repairs and restarts. If not, the issue often stems from hardware malfunctions or driver software problems. Common causes include:
1. Software reason

● Outdated or incompatible device drivers.

● Corrupted system files.

● Virus/malware intrusion.

● Outdated BIOS.

2. Hardware reasons

● If the CPU/GPU fan is faulty, it may cause a blue screen when the computer is overheated.

● The computer does not have sufficient storage space when installing/upgrading the operating system.

● Affected by interference from external devices such as flash drives, external hard drives, etc.

● Loose hardware/cables.

● Some hardware may be damaged or expired.

III. Solution to the blue screen when Windows can be restarted

Solution 1. Use System Restore to Undo Recent Changes

Windows System Restore is an invaluable troubleshooting tool that reverts your computer to a previous state when it was functioning correctly. This utility automatically generates restore points prior to critical actions such as new application installations, driver updates, or significant system changes. Additionally, you have the option to create restore points manually. It’s worth noting that using System Restore will not affect personal files such as emails, documents, or photos. However, it will remove any apps, drivers, and updates that were installed after the chosen restore point.
The specific operation steps are as follows:
① Click the “Start” button in the lower left corner of the screen or search in Cortana. In the search box, enter “system restore“. Then click “Create Restore Point” on the search results page.

② In the opened window, select the drive you want to restore, and then click “System Restore“.
System Restore Point thumb
③ Select any existing restore point and click “Next”.
select the restore point
④ After confirming all the information, click “Finish” > “OK”. If you don’t get a blue screen after this, your problem may be software related.

Solution two: Scan for malware and viruses

Malware causing damage to Windows system files frequently leads to a blue screen. Viruses that attack the master boot record (MBR) or boot sector are known to cause blue screens of death (BSOD). To mitigate this risk, it is crucial to regularly use a robust antivirus software to scan your system for potential threats. Always make sure your antivirus is updated to the latest version before initiating the scan process.

Solution three: Check your computer for hard drive and memory errors

Encountering a blue screen error can often be attributed to problems with your computer’s hard disk or RAM. Windows is equipped with a built-in hardware detection and repair tool, which can be utilized for preliminary self-diagnosis. To run this tool, execute the chkdsk command for hard disk issues, or mdsched.exe for memory problems. Should the issue persist after your initial efforts, it is advisable to contact the hardware manufacturer for further assistance.
1. Check for Hard Drive Errors
Windows 10′s built-in disk check tool can fix logical errors, but it cannot repair physical bad sectors on a hard disk.
The specific operation steps are as follows:
① Double-click “Computer/This PC”, right-click the target hard drive, and select “Properties”. Choose the “Tools” tab and click “Check”. If prompted, input the administrator password and confirm.

IV. Solution to the blue screen when Windows cannot be restarted

If your computer fails to restart following a blue screen error, consider these steps: boot into Safe Mode to troubleshoot and resolve software issues, use system restore points to revert to earlier settings, or perform a repair installation of Windows to fix corrupted system files without affecting personal data. If these methods don’t work, you may need to reset or reinstall Windows as a last resort.

Solution 1: Try to start Windows in Safe Mode

If your computer won’t start normally, booting in Safe Mode can help troubleshoot issues. Safe Mode starts Windows with minimal files and drivers, preventing third-party software interference. This allows you to detect and fix system errors, uninstall problematic programs, and isolate the cause of software-related blue screens of death. If Safe Mode boots successfully, it suggests that default settings and basic drivers aren’t the issue, narrowing down the potential problem sources.
The steps for Windows to enter safe mode are as follows:
● Windows 10/8/8.1 operating system
① To enter safe mode, access the Windows Recovery Environment (winRE) by pressing the power button to turn your computer on and off before the boot logo shows. Do this three times. Then, on the “Choose an option” screen, go to “Troubleshoot” > “Advanced Options” > “Startup Settings” and select “Restart“.
