When Windows encounters a condition that compromises safe system operation, the system halts. This condition is called a bug check. It is also commonly referred to as a system crash, a kernel error, or a stop error or Blue Screen of Death(BSOD).

If Windows is allowed to continue to run after the operating system integrity is compromised, it could corrupt data or compromise the security of the system.

Usually, you may see a blue screen while upgrading to a new version of Windows 10, during startup, or while actively using the computer.

In Windows 10, you can troubleshoot BSOD information. Navigate to Control Panel > Security and Maintenance. In the “Maintenance” section, you’ll be able to check for solutions to existing problems.

By default, Windows automatically restarts the computer whenever it encounters a blue screen of death. Windows 10 actually performs automatic troubleshooting when your PC restarts after a BSOD. However, if Windows can’t fix the problem on it’s own, click here for the online Blue Screen Troubleshooter from Microsoft.
