BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
The original Blue Screen of Death (here seen in the Italian edition of Windows NT 3.51) first appeared in Windows NT 3.1. The first Blue Screen of Death appeared in Windows NT 3.1 [5] (the first version of the Windows NT family, released in 1993), and later appeared on all Windows operating systems released afterwards.
Overclocking beyond the highest clock rate at which the CPU is still reliable. Failing motherboard. Failing processor. Failing memory. Failing I/O controllers, on either the motherboard or separate cards. Failing I/O devices. Inadequate or failing power supply. Cooling problems are usually obvious upon inspection.

Ralf Brown's Interrupt List (aka RBIL, x86 Interrupt List, MS-DOS Interrupt List or INTER) is a comprehensive list of interrupts, calls, hooks, interfaces, data structures, CMOS settings, memory and port addresses, as well as processor opcodes for x86 machines from the 1981 IBM PC up to 2000 (including many clones), [1] [2] [nb 1] most of it still applying to IBM PC compatibles today.
The detection of a RESET signal causes the processor to enter a system initialization period of six clock cycles, after which it sets the interrupt request disable flag in the status register and loads the program counter with the values stored at the processor initialization vector ($00FFFC – $00FFFD) before commencing execution. [1]
INT is an x86 instruction that triggers a software interrupt, and 13 hex is the interrupt number (as a hexadecimal value) being called. Modern computers come with both BIOS INT 13h and UEFI functionality that provides the same services and more, with the exception of UEFI Class 3 that completely removes CSM thus lacks INT 13h and other interrupts.
