The WHEA_UNCORRECTABLE_ERROR is a typical hardware-related blue screen error in Windows, with error code 0x00000124, indicating that Windows has detected a critical, unrecoverable hardware error.

Troubleshooting and Solutions

Blue screens caused by WHEA_UNCORRECTABLE_ERROR are almost certainly due to underlying hardware issues; potential causes include temperature problems, unstable overclocking, hardware failures, or power supply issues.

Start with simple methods and troubleshoot step by step. If the error occurs during high load (such as when gaming with CPU/GPU under heavy workload), first consider reducing clock speeds and checking cooling/power supply:

  • Check Temperatures

    Use monitoring tools to check if CPU/GPU temperatures are too high;

    If temperature-related, inspect cooling systems, clean dust, and replace thermal paste.

  • Check Overclocking and Power Supply

    Try reducing CPU, GPU, and RAM frequencies; for crashes under high load, verify if power supply capacity meets system requirements - consider replacing PSU if insufficient.

  • Remove Recently Added Hardware

    If blue screens began after adding/replacing hardware, try removing or replacing these components; may indicate hardware failure or incompatibility.

  • Hardware Inspection

    First check for loose connections - reseat hardware components.

    Inspect hardware for physical damage or abnormalities.

    Use diagnostic tools to test individual hardware components.

If blue screens occur frequently without discernible pattern, seek professional repair assistance.
