Whether you were installing Windows 10, applying a Windows Update, or using your computer normally, you receive a Blue screen of death with a STOP error that reads WHEA_UNCORRECTABLE_ERROR. In this post, we will explain what this particular BSoD STOP error tells us and how to fix the issue in Windows 11 or Windows 10.
The Whea Uncorrectable blue screen error may occur randomly and forcibly shut down your computer to protect your Window from losing data. This will happen when Windows detects hardware error when running the OS. It could be due to hardware failure, incorrect or faulty drivers.
How to fix WHEA_UNCORRECTABLE_ERROR
Whea Uncorrectable Error during Windows Installation – Some users tend to get the STOP error during Windows 11 or 10 installation. If you’re fresh installing Windows, it could mean that there is a hardware which begins to fail and the error occurs to prevent data loss.
Whea Uncorrectable Error After Windows Update – Users also receive the STOP error immediately after installing a recent Windows Update (particularly the Windows October 2018 update version 1809, or may also happen in any future update). This could be due to incorrectly installed driver from Windows Update itself, or hardware failure happened during the update.
Whea Uncorrectable Error due to Overclock 0xc0000124 – Since the STOP code indicates hardware error in your computer, the error would also show up if your hardware, especially your processor, graphic card or RAM is incorrectly overclocked.
The WHEA_UNCORRECTABLE_ERROR BSOD could also occur in some Dell laptops while gaming, causing an instant interruption and a force shut down of your PC.
To summarize all the occurrence, the WHEA_UNCORRECTABLE_ERROR STOP code error points toward one single cause – hardware error or damaged hardware. You’ll have to figure out which hardware in your system that is failing (or has the highest chance to fail) and causing the issue. To find out the cause of the error, use the fixes listed below to troubleshoot your computer.
Stop overclocking your hardware
If you have previously overclock any of your hardware, try to temporary disable the overclock settings and set your hardware’s clock speed back to its default value.
Depending on how to overclock your processor, RAM or graphic card. You may need to restore the default clock value via BIOS settings or simply by turning off or uninstalling the overclock software if you’re using any.
The screenshot above is just an example of the clock speed setting in a specific BIOS interface. Yours might be different.
Run Windows Update
If you’re getting the blue screen randomly after installing Windows, run Windows Update now to receive the latest bug fixes and most importantly to update your drivers with the latest driver from Windows repository.
To run Windows Update in Windows 11/10, go to start menu. Type Windows Update and open it. Click check for updates to begin updating your Windows.
Manually update your hardware drivers
If your case is you get the error only after Windows update, it could mean that a driver installed by Windows Update is causing conflicts between the OS and the driver.
Try to manually download and install drivers from your manufacturer’s website. For example, if you are using Nvidia or ATI graphic card, go to their website and download the latest drivers respectively.
If you owns a specific brand of laptop, for instance Dell, check on Dell’s driver site and install the latest drivers available. Hardware which you should check for latest drivers: Graphic card, network adapters, and motherboard chipset driver. Though if you have a specific keyboard, mouse, hard disk drive, or any other peripherals, do check their drivers too.
This is assuming you can access to the safe mode in order to install these drivers. To enter safe mode without getting into Windows first, read: How to enter safe mode in Windows 11/10 if your Windows is corrupted.
Run CHKDSK to check for HDD error
CHKDSK command is able to scan and repair disk error for your hard drive. To be able to run these commands, we need to boot into Windows recovery.
If you can’t boot into Windows, force restart your computer as soon as you see the error for 3 times. Windows will then boot into Windows recovery. From there, navigate to Troubleshoot > Advanced options > Command Prompt. Then, enter the following command.
chkdsk c: /f
If your operating system was installed in another drive, replace C: with your OS primary drive’s letter.
In the meanwhile, you may also want to run several other repair tools to see if they help to fix the Whea Uncorrectable Error. Run the following commands one line at a time in an elevated command prompt.
Dism /Online /Cleanup-Image /RestoreHealth
These tools may take some time to run. For more info about what these tools do, read: How to Startup Repair Windows 11 or 10 using Command Prompt.
Run Windows Memory Diagnostic
Windows memory diagnostic is capable of identifying and diagnosing problems with your memory (RAM). If the test result indicates a problem with your memory, you may need to replace your RAM pieces.

If you have no access to your Windows, follow the steps in the previous section about how to enter Windows Recovery. Once you’re there, open Command prompt and enter mdsched.exe.
If nothing works to solve the Whea Uncorrectable Error blue screen issue on your PC, try to reset your Windows.
