The full form of BSOD is Blue Screen of Death . It’s used on Computing ,General Computing in Worldwide

Blue Screen of Death (BSoD‎) is a stop error or exception error, commonly called the blue screen of death (BSoD) or blue screen, is an error screen displayed on Windows computers following a fatal system error. It indicates a system crash, in which the operating system has reached a condition where it can no longer operate safely. This is caused by many different problems, such as a general hardware failure or a crucial process terminating unexpectedly.

On Windows 10, a Blue Screen of Death (BSoD) — also known as “blue screen,” “stop error,” or “system crash” — will always happen after a critical error occurs, which the system is not able to handle and resolve automatically.

Usually, you’ll experience a blue screen error during the upgrade process of Windows 10, during startup, or randomly when actively using your laptop or desktop. The most frustrating part of all is that you’ll only see a solid blue background and a sad character face without enough valuable information to determine the real cause of the problem.

The screen will output a hint message, such as “Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you.” Or general stop error codes (such as VIDEO_TDR_TIMEOUT_DETECTED, PAGE_FAULT_IN_NONPAGE_AREA, CRITICAL_PROCESS_DIED, SYSTEM_SERVICE_EXCEPTION, DPC_WATCHDOG_VIOLATION, or IRQL_NOT_LESS_OR_EQUAL). Or hexadecimal codes (such as 0x000000D1, 0x0000000A, or 0x0000007B), but they’re just hieroglyphics for most users.
