BSOD The 'Blue Screen of Death' (also known as a 'stop error', 'bluescreen', 'Blue Screen of Doom', 'BSoD', 'bug check screen' or 'Stop screen') is an error screen displayed after a fatal system error.
BSoDs have been present in all Windows-based operating systems since Windows 3.1. (See History of Microsoft Windows.) BSoDs can be caused by poorly written device drivers or malfunctioning hardware, such as faulty memory (computers)|memory, power supply issues, overheating of components, or hardware running beyond its specification limits. In the Windows 9x era, incompatible Dynamic-link library|DLLs or bugs in the operating system Kernel (computer science)|kernel could also cause BSoDs.
In a follow up on 9 September 2014, Raymond Chen complained about this widespread mistake, claimed responsibility for revising the BSoD in Windows 95 and panned BGR.com for having entirely fabricated a scenario and posited it as real
BSOD - Format For visually impaired users, Microsoft has added a utility that allows the user to change a setting in SYSTEM.INI that controls the colors that the BSoD code uses to any of the 16 CGA colors
BSOD - Format Windows 95, 98 and Me BSoDs use 80×25 text mode. BSoDs of Windows NT family use 80×50 text mode on a 720×400 screen. Windows XP BSoDs uses the Lucida Console font while the Vista BSoD uses the Consolas font. Windows Server 2012 uses Segoe UI and renders the BSoD at native resolution.
BSOD - Windows NT Microsoft Windows can also be configured to send live debugging information to a kernel debugger running on a separate computer. If a stop error is encountered while a live kernel debugger is attached to the system, Windows will halt execution and cause the debugger to break in, rather than displaying the BSoD. The debugger can then be used to examine the contents of memory and determine the source of the problem.
BSOD - Windows NT A BSoD can also be caused by a critical boot loader error, where the operating system is unable to access the boot partition due to incorrect storage drivers, a damaged file system or similar problems
BSOD - Details Before Windows Server 2012, each BSoD displayed an error name in uppercase (e.g. APC_INDEX_MISMATCH), a hexadecimal error number (e.g. 0x00000001) and four parameters. The last two are shown together in the following format:[http://msdn.microsoft.com/en-us/library/ms818748.aspx STOP: 0x00000001 (parameter, parameter, parameter, parameter) APC_INDEX_MIS]
BSOD - Windows 9x However, VxDs do not display BSoDs frivolously — they usually indicate a problem that cannot be fixed without restarting the computer, and hence after a BSoD is displayed the system is usually unstable or unresponsive.
BSOD - Windows 9x The most common BSoD is on a 25×80 screen which is the operating system's way of reporting an interrupt caused by a processor exception; it is a more serious form of the general protection fault dialog boxes. The memory address of the error is given and the error type is a hexadecimal number from 00 to 11 (0 to 17 decimal). The error codes are as follows:
BSOD - Windows 9x In Windows 95 and 98, a BSoD occurs when the system attempts to access the file c:\con\con or c:\aux\aux on the hard drive. This could be inserted on a website to crash visitors' machines. On 16 March 2000, Microsoft released a security update to resolve this issue.
BSOD - Windows 9x In these systems, the true BSoD is seen only in cases where the entire operating system crashes.
BSOD - Windows 9x A famous instance of a Windows 9x BSoD occurred during a presentation of a Windows 98 Beta software|Beta by Bill Gates at COMDEX on April 20, 1998: The demo PC crashed with a BSoD when his assistant, Chris Capossela, connected a scanner to the PC to demonstrate Windows 98's support for Plug and Play devices. This event brought thunderous applause from the crowd and Gates replied after a nervous pause: That must be why we're not shipping Windows 98 yet.
