Blue Screen WHEA_UNCORRECTABLE_ERROR in Windows: Causes and Fixes

The Blue Screen of Death (BSOD) with the error WHEA_UNCORRECTABLE_ERROR is one of the most frustrating issues that Windows users may encounter. This error points to serious hardware or driver problems, making it impossible for the system to continue running. In this guide, we’ll explore what this error means, why it happens, and how you can fix it.

What Does WHEA_UNCORRECTABLE_ERROR Mean?

The error code WHEA_UNCORRECTABLE_ERROR (0x00000124) indicates a critical hardware failure detected by the system. WHEA stands for Windows Hardware Error Architecture, which is a Windows feature designed to handle hardware errors. When Windows detects a hardware issue that cannot be corrected by software, it triggers a blue screen with this error message.

Main Causes of WHEA_UNCORRECTABLE_ERROR

  • Overheating of the CPU or GPU: High temperatures can cause component failures, leading to critical errors.
  • Faulty RAM: Memory errors are a common cause of system crashes and BSODs.
  • Driver Issues: Outdated or incompatible drivers can cause conflicts, especially after a Windows update.
  • Overclocking: Overclocking the CPU or GPU can make the system unstable and result in a critical error.
  • Hard Drive or SSD Failures: Problems with storage devices, like bad sectors, can lead to system crashes.

How to Fix WHEA_UNCORRECTABLE_ERROR

Before you begin troubleshooting, it's a good idea to back up your important data as this error might recur and make it difficult to access your system.

1. Check Hardware Health

Start by checking the health of your key components:

  • Check CPU and GPU Temperatures: Use tools like HWMonitor or Core Temp to monitor temperatures. If components are overheating, clean your system and ensure proper cooling.
  • Run Memory Diagnostics: Use the built-in Windows Memory Diagnostic Tool or third-party programs like MemTest86 to check for RAM errors.
  • Check Storage Devices: Run the command chkdsk /f /r in the Command Prompt to scan and fix errors on your hard drive or SSD.

2. Update Drivers

Outdated or incorrect drivers are a common cause of the WHEA_UNCORRECTABLE_ERROR. It's recommended to update drivers for all major components:

  • Open Device Manager and check for devices with warning signs (yellow exclamation marks).
  • Update drivers through Windows Update or download them from the manufacturer’s website.

3. Disable Overclocking

If you have overclocked your CPU, GPU, or RAM, consider resetting them to their default settings. Overclocking can often lead to instability, especially if cooling is insufficient.

4. Check BIOS/UEFI

An outdated BIOS or UEFI can sometimes cause this error. Check the manufacturer’s website for updates and proceed with caution if you decide to update your BIOS, as an incorrect update can render your system unusable.

5. Use System Restore

If the error started appearing recently, try restoring your system to an earlier point in time:

  1. Open the Start menu and type System Restore.
  2. Select Open System Restore and follow the on-screen instructions.
