BSOD with WHEA_UNCORRECTABLE_ERROR pointing to a failing or improperly seated CPU

The problem: System crashes with WHEA_UNCORRECTABLE_ERROR, a hardware-level error correction failure, potentially indicating CPU, motherboard, or power delivery issues.

Symptoms: BSOD occurs unpredictably, sometimes during load and sometimes at idle; may be accompanied by brief freezes or graphical glitches prior to crash; WHEA errors logged in Event Viewer even outside full crashes.

Likely cause: CPU or chipset detected an uncorrectable hardware fault — CPU instability (often overclocking-related), failing power delivery component (VRM issues), improper CPU seating, or genuine CPU degradation/failure.
