what is BSOD(Blue Screen Of Dead)?

What is the Blue Screen of Death?
The Blue Screen of Death, or simply BSOD, represents an error notoriously associated with Microsoft Windows operating systems. This error is more common on older versions of Windows such as 3.0 and 3.1, but also shows up on later versions such as Windows 95, 98, NT, 2000, XP, and even Vista. Although the Windows platform has come a long way in terms of stability and performance, the infamous Blue Screen of Death is still known to make an entrance from time to time. When this nuisance shows up, it often indicates that the system has a critical error.

Identifying the Blue Screen of Death
As the name implies, the Blue Screen of Death is characterized by a blue screen along with text and hexadecimal values that help to determine what caused the problem. When a BSOD occurs, the system is essentially shutting down to protect itself from a particular error. Unfortunately, it often leads to the loss of any data that was not saved before the computer crash occurred.
After encountering the Blue Screen of Death, your computer might automatically shut down or you may be forced to shut it down manually. Once this process is complete, the machine is rebooted and the system typically runs a diagnostics to retrieve data and determine what led to the error.
If you are bombarded with a BSOD error repeatedly, it could be a sign that your computer system is enduring serious problems. When this is the case, you may need to perform a re installation of the operating system or take various troubleshooting steps in order to pinpoint and resolve the issue. Some of these steps may need to be performed in Safe Mode, which provides a stripped down version of the Windows operating system and features an environment that lets you safely troubleshoot various issues.
Analyzing BSOD Codes
Unless you are a computer programmer, the data that is displayed on the blue screen will probably look like unfamiliar gibberish. However, this information is incredibly useful in solving your problems. These codes generally identify the error and its parameters among other details that could help you pinpoint the problem and keep it from occurring again. A knowledgeable computer user can access the information accompanying the Blue Screen of Death and quickly determine the root of the problem. Most of the time, they come to find that it has something to do with the kernel of the operating system, or a hardware device installed on the computer.
Inherent Problems with Computer Systems
Unless you started your computing with newer versions of XP or Vista, you have probably encountered the dreaded Blue Screen of Death with more frequency then you prefer. This is especially true for someone running a more unstable version of the system or one who has made significant modifications to the Windows environment. Although the Windows system has been known for the infamous blue screen and other deficiencies, it isn’t the only platform that endures critical errors. Both Mac OS X and Linux computers encounter similar problems known as Kernel Attacks.
