What is WHEA_UNCORRECTABLE_ERROR?

The WHEA_UNCORRECTABLE_ERROR error is categorized as a critical-severity processor (CPU) issue that can significantly impact your PC's stability. Critical CPU or chipset hardware error (BSOD 0x124). Caused by voltage instability, overheating or overclocking. When experiencing the WHEA uncorrectable error fault, users often report sudden system crashes, unresponsive behavior, or a blue screen of death (BSOD). In most diagnostic scenarios, this problem is directly triggered by underlying hardware or software complications such as cpu overheating, unstable vcore voltage, overclocking beyond limits and defective ram. To permanently resolve the WHEA_UNCORRECTABLE_ERROR issue and prevent further system degradation, it is highly recommended to follow our step-by-step troubleshooting guide below, ensuring your processor (CPU) components are functioning correctly.

Common Causes
