The Blue Screen Of Death (also known as BSoD or bluescreen or “Blue Screen of Doom”), known officially as a Stop Error or a bug check is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to “crash.” The term is named after the color of the screen generated by the error.
Stop errors are usually hardware or driver related, causing the computer to stop responding in order to prevent damage to the hardware, whereupon, in the latest versions of Windows, the screen presents information for diagnostic purposes that was collected as the operating system performed a bug check. If you encounter one of these errors, write down the code number and title (in all caps) to provide to a technician. Blue screen errors are to be expected occasionally, but if you are receiving them with any frequency, contact a professional before continuing to use the computer.
Since stop errors are considered “fatal errors,” they are not always easily fixed. There are broadly two ways to fix these errors, depending on the nature of the error: either a hardware component needs to be repair/replaced or the operating system needs to be restored. Solving this type of error often requires the operating system to be reinstalled.
