Blue screen

A "blue screen," often referred to as the "Blue Screen of Death" (BSOD), is an error screen displayed by Windows operating systems when a critical problem occurs that prevents the system from operating safely. It typically indicates a severe issue, such as hardware failure, driver conflicts, or corrupted software. When this happens, the operating system shuts down to prevent further damage. The screen contains technical information about the error, which can help in diagnosing the issue, but for most users, it signifies a need for troubleshooting or professional assistance.
