The WHEA_UNCORRECTABLE_ERROR is a critical error message (with a stop code of 0x00000124) that appears on a Blue Screen of Death (BSOD) in Windows 10 and Windows 11. This error indicates a severe hardware error detected by the Windows Hardware Error Architecture (WHEA) framework.
Encountering a BSOD can be alarming, but resolving it is possible with a methodical approach. This article offers a detailed guide to diagnose and fix the WHEA_UNCORRECTABLE_ERROR effectively.
Understanding the Causes of WHEA_UNCORRECTABLE_ERROR
The WHEA_UNCORRECTABLE_ERROR typically occurs due to:
- Hardware malfunctions (CPU, GPU, RAM, Hard Disk)
- Overheating and cooling system failure
- Driver conflicts or outdated drivers
- Overclocking instability
- Corrupted system files
- Voltage supply issues
Step-by-Step Troubleshooting Guide
1. Check for Overheating
Overheating is a frequent cause of critical hardware shutdowns.
To check CPU temperature:
- Enter BIOS/UEFI by pressing the appropriate key (F2, F10, F12, or Del) during boot.
- Look for CPU temperature readings.
2. Run Hardware Diagnostics
Most manufacturers like Lenovo, Dell, and HP provide built-in diagnostics tools to detect hardware faults.
Example: On Lenovo laptops, press F12 during startup ➔ Launch Diagnostics ➔ Run Memory and Storage Tests.
3. Update Drivers and Firmware
Driver conflicts are a major BSOD cause. Update your drivers regularly:
- Open Device Manager (Windows key ➔ Search “Device Manager”).
- Right-click on devices and select Update driver.
4. Disable Overclocking
If you have overclocked your CPU or GPU, revert all settings to default. Overclocking can cause instability even with moderate temperature increases.
5. Run System File Checker (SFC) and Check Disk (CHKDSK)
Repair Windows system files to eliminate corruption:
- Open Command Prompt as Administrator.
- Run the command: sfc /scannow
After SFC completes, run: chkdsk /f /r to check for hard drive issues.
6. Memory and Hard Drive Tests
Faulty RAM can lead to random BSODs. Test your RAM and disk health:
- Search for and open Windows Memory Diagnostic.
Click “Restart now and check for problems“. Your computer will reboot and test memory automatically.
Additional Tips to Prevent WHEA_UNCORRECTABLE_ERROR
- Keep Windows updated regularly.
- Replace thermal paste every 2–3 years for optimal cooling.
- Invest in a quality PSU (Power Supply Unit) with stable voltage output.
- Use high-quality RAM modules compatible with your motherboard.
- Monitor CPU temperatures with tools like HWMonitor.
When to Seek Professional Help?
If hardware diagnostics show a failing CPU, GPU, RAM, or motherboard component, or the issue persists even after following all troubleshooting steps, it’s time to contact a certified technician or the manufacturer’s service center.
