What are Blue Screen of Death and Black Screen of Death? Do they mean the End of your Computer?
Both of these signify a computer crash.
They are most associated with pre Windows 2000 releases as when a crash occurred, the information pertaining to the crash would often be displayed on a cyan background.
The mysticism was, if it knew what was wrong, why did it go ahead and crash?
Since Win 2K, I have not seen this, but if problems hang over on shutdown, sometimes, the system startup can be preceded by a blue screen where the discs are checked before commencing the OS system startup.
They rarely mean the end of your computer, but more suggest that something went wrong that it couldn't get over. Usually a reboot cleared all that.
Blue screen of death is associated with windows
Black screen of death is normally associated with Mac and linux
They both mean the system has crashed from an unrecoverable error
Very commonly this is just a graphics card or RAM issue that will be fixed with a restart
Sometimes this will be a more serious processor or hard drive issue, which won't always be fixed with a restart
Either case, its not the end of your computer, normally a restart will clear it up, worst case you have to replace a component of your computer
Blue screen of death:
The Blue Screen of Death (also known as a stop error, BSoD, bluescreen, or Blue Screen of Doom) is a colloquialism used for the error screen displayed by some operating systems, most notably Microsoft Windows, after encountering a critical system error that can cause the system to shut down to prevent irreversible damage to the system's integrity. It serves to present information for diagnostic purposes that was collected as the operating system issued a bug check.
If so configured, the system will dump all of its memory to a file on disk. Data in memory would then be lost but in some circumstances it could be retrievable from the dump file, a process that must be carried out by a trained PC technician.
Black screen of death: The black screen of death (BlSoD) is a colloquialism used for the black error screen displayed by some operating systems after encountering a critical system error which can cause the system to shut down to prevent damage.
But "blue screen of death" and "black screen of death" can not be permanent these errors can be fixed by proper guidence and steps.
Recent versions of Windows all run their programs (processes) in a separate space in memory so they can't affect each other. In theory, if a program crashes, just that program dies and it doesn't bring down the others.
But sometimes a program will so corrupt the memory that it affects the mechanism that keeps these processes separate. At that point, the operating system can't prevent a crash bringing down the whole system.
Some programs are privileged and get greater access to the operating system code. Examples are drivers for hardware. If one of those drivers misbehaves and crashes, it can potentially bring down the operating system. Windows is designed to provide a Stop screen which contains details of which process was running, what memory addresses were involved, and also dumps a trace of some of the recent program calls. That helps software engineers diagnose the cause. But it doesn't help the user. They have to reboot and potentially experience it all over again.
The most likely cause of Windows BSoD screens are driver problems. Next most likely is memory errors on the memory chips in the machine which are replaceable. Sometimes, it can also be caused by hard disk errors where the area on the HD contans operating system code. If you look carefully at the Stop screen, you can sometimes see mention of which driver it was. That can give you a clue as to which device is causing the problem. Disconnect it, download the latest driver and install it, then reuse the device. Often that's enough to solve the problem.
Windows 7 is not immune from BSoDs as is evidenced by the latest scare stories.
