BSOD: Blue Screen of Death

On Microsoft Windows-based computers, such failures often result in the appearance of a solid blue screen containing a cryptic message in white letters. Your machine suddenly stop working and had blue on screen with some text. This situation called the "Blue Screen of Death" or BSOD. This condition mean, Windows operating system encounters an error from which it cannot recover, and BSOD is displayed.

This condition caused by hardware problems that generate a BSOD include fault on memory, failed disk drive, or an excess of dust on the circuit boards inside the computer. Beside hardware problem, BSOD can caused by Software failures that often lead to BSODs
involve improperly-installed, obsolete, defective, or otherwise faulty drivers.

Driver software is the code that tells Windows about hardware device and how to control it. Other problems, could arise from improperly configured registry settings or fault on installation of Windows. Poorly written application software can also trigger the BSOD, although that is increasingly rare.

Some simple steps that can help you track down problems and save a trip to repair shop:

* BSOD caused by resulted trying to use a specific piece of hardware, look for visual indicator such as lights coming on, disk spinning, etc. Other way, try to clean some connector hardware (memory, VGA card, sound card, modem internal, or other hardware that you plug in to your computer.
* BSOD caused by software device driver, use installation disk that came with it. Update the driver to the most recent version from vendor.
* BSOD can caused by overheat of processor or chipset or microchip. Check cooling device on circuit board or motherboard. Any particular activity or piece of hardware, feel the computer case. Check to make sure PC's fans are working.
* Malware or accident instalation some software that not match sIf the computer case is not hot, try running a virus scan. There are several anti-virus products available that should identify the virus and remove it.

Should none of these techniques work and the problem persists, the failure may be related to problems with the RAM or hard drive. For most of us, this means it is time to back up our critical data and seek out a repair facility. More information about BSOD:
