WHEA_UNCORRECTABLE_ERROR (0x124)

What is 0x00000124?

The 0x00000124 error is categorized as a critical-severity processor (CPU) issue that can significantly impact your PC's stability. The Windows Hardware Error Architecture (WHEA) has detected an uncorrectable hardware exception. Most commonly caused by CPU core voltage instability, overheating cores, unstable memory profiles (XMP/EXPO), or physical damage to the processor socket. When experiencing the 0x00000124 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, and unstable RAM. To permanently resolve the 0x00000124 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

• CPU core voltage (Vcore) drop under load
• Processor thermal throttling and overheating
• Unstable RAM overclock (XMP/EXPO profiles)
• Power Supply Unit (PSU) voltage sags

Step-by-Step Fix Guide

• 1
  Reset BIOS settings to system defaults

  Applying the first fix (Reset BIOS settings to system defaults) addresses the most common root cause of 0x00000124 and restores baseline functionality.

• 2
  Monitor temperatures using HWInfo or HWMonitor

  If the problem persists, proceeding with the remaining steps ensures all edge cases related to cpu instability are covered.

• 3
  Run memory diagnostics using MemTest86
• 4
  Check 12V voltage rail stability under load
