Quick Answer

"UNMOUNTABLE_BOOT_DEVICE" is a STOP code that refers to errors in the file structure of the hard drive disk on which the operating system is running. If the operating system can be restarted, there are tools available to diagnose the hard drive error in a more specific fashion.

The STOP code "DRIVER_IRQ_NOT_LESS_THAN_OR_EQUAL_TO" appears when the software for a vital device attached to the computer fails, causing a driver interrupt request. Typically, a bug within the driver software itself causes this error. Correcting the error requires booting into safe mode, removing the driver and installing an older or more reliable driver instead.

"PAGE_FAULT_IN_NON_PAGE_AREA" is a STOP code that serves as a blanket error message encompassing a wide variety of problems. For error codes such as these, supplemental error messages may explain the specific cause of the crash.
