It is a routine called when the kernel detects irrecoverable errors in runtime correctness; in other words, when continuing the operation may risk escalating system instability, and a system reboot is easier than attempted recovery.
A BSoD can also be caused by a critical boot loader error, where the operating system is unable to access the boot partition due to incorrect storage drivers, a damaged file system or similar problems.
Rarely an experienced user would reinstall Windows. In the case of the former, the boot loader will most likely inform the user the name of the missing file, allowing for the user to supply and/or reinstall the missing files to resolve the boot problem. In the case of the latter, however, the computer will not be able to boot, even into safe mode.
