X64 Exception Type 0x12 Machinecheck Exception Link _best_ <Best>

An x64 Exception Type 0x12, universally known as a Machine Check Exception (MCE), is a critical hardware error detected by the processor. When this error occurs, the Central Processing Unit (CPU) determines that a hardware failure has occurred which threatens system stability, prompting an immediate operating system crash (often resulting in a Blue Screen of Death in Windows or a Kernel Panic in Linux).
