CPU overheating, causing the processor to shut down or trigger an exception to prevent permanent damage.

The x64 Exception Type 0x12, or Machine Check Exception (#MC), is a critical, often fatal, hardware-level error indicating a failure in the CPU, memory, or PCIe bus. Troubleshooting typically involves updating BIOS/firmware, reverting overclocks, and reviewing system logs via HPE iLO or Windows Event Viewer.

An is a Machine Check Exception (MCE) , which occurs when a processor's Machine Check Architecture (MCA) detects an unrecoverable hardware error . On server systems like the HPE ProLiant Gen10 , this typically triggers a Red Screen of Death (RSOD) and indicates a failure that the OS cannot handle. Common Root Causes

Problems with communication between the processor and the motherboard or uncorrectable PCI Express (PCIe) errors.

Elias knew this wasn't a simple software glitch. This exception meant the processor had detected a fatal hardware anomaly—an internal machine error, a bus failure, or an external agent shouting that the communication lines had collapsed.

Inadequate voltage from the power supply or failing voltage regulators on the motherboard. Troubleshooting & Resolution Advisory: Apollo 6500 Gen10 - HPE Support
