The WHEA_UNCORRECTABLE_ERROR (stop code 0x00000124) is a critical failure of the Windows Hardware Error Architecture. Unlike many other Blue Screen of Death (BSoD) errors, this one indicates a hardware issue in 90% of cases, rather than a software glitch.

Main Causes of the Error

The system protects itself to prevent physical damage to the components. The primary culprits are: * Overheating of the processor (CPU) or graphics card (GPU). * Unstable overclocking or enabled XMP profiles for RAM. * A faulty power supply unit (PSU) causing voltage spikes. * Physical wear and tear of the system drive (SSD/HDD).

Step-by-Step Solution

Step 1: Disable Overclocking

If you have overclocked your CPU or RAM, revert to the base settings. 1. Restart your computer and enter the BIOS/UEFI (usually by pressing Del or F2). 2. Find the Load Optimized Defaults option or manually reset the CPU and RAM frequency settings (disable XMP). 3. Save the changes (F10) and reboot.
⚠️ Before updating or resetting the BIOS, ensure your computer is connected to a reliable power source (ideally through a UPS). A sudden power outage while working in the BIOS can brick your motherboard.

Step 2: Check System Files and Disk

If the BIOS is reset but the error persists, check the integrity of the file system. Open the Command Prompt as an Administrator and type the following commands one by one: * chkdsk /f /r (requires a reboot to scan the disk). * sfc /scannow (system file check).
ℹ️ Pro Tip

The WHEA error often occurs after installing new RAM sticks. If you recently upgraded your memory, try removing the modules, wiping the contacts with a regular eraser, and pushing them back in until you hear a distinct click.

❓ Will reinstalling Windows fix this error?

Usually, no. Because the error is hardware-related, reinstalling the OS (Windows 10 or 11) will only be a temporary fix, and the blue screen will return during the first heavy load on the processor or disk.
