A blue screen error (also called a stop error) can occur if a problem causes your PC to shut down or restart unexpectedly (aka: crash). When you experience this type of error, you wonâ€™t be able to see things like the Start menu or the taskbar on the screen when your PC is turned on. Instead you might see a blue screen with a message that your PC ran into a problem and needs to restart.
Windows has a hidden feature that you can enable to be able to manually force a BSOD by holding down the rightmost Ctrl key, and press the Scroll Lock key twice.
When used, the system calls KeBugCheck and issues bug check 0xE2 (MANUALLY_INITIATED_CRASH). Unless crash dumps have been disabled, a crash dump file is written at this point.
This tutorial will show you how to enable or disable to manually force a BSOD crash on Ctrl+Scroll Lock in Vista, Windows 7, Windows 8, and Windows 10.
