Blue screen error codes is the term used for an error screen shown by some operating systems, including Microsoft Windows. When a system encounters problems that might cause damage in the future, the blue screen error code prevents it from occurring. Its function is to introduce information for problem-solving intention.  Blue screens on Windows systems are customarily triggered by poorly-written device drivers or faulty hardware. Mismatched bugs in the operating system could also cause these screen error codes. They can also be caused by physical defect such as faulty memory, defective  power supplies, overheating of computer components, or hardware operating beyond its required restrictions.
