The BSOD is one type of Windows error message. With its bright blue background and white text, the BSOD is hard
to miss.
Various types of errors may cause a BSOD. For example, a bad device driver, a hardware conflict, or even an error in the Registry may prompt a BSOD.
One of the most common causes of a BSOD is that Windows can’t boot from the hard drive. Corrupted data on a hard drive can cause
a BSOD, as can the installation of incompatible memory modules.
The most common type of BSOD is a fatal exception error, an error that forces the current application to shut down. This happens when an unexpected event, or exception, occurs.
If no code exists to handle the exception, the program cannot proceed, and Windows will display a fatal exception error message.
