WHEA Uncorrectable Error – How to troubleshoot

A blue screen error of death has been around for a long time. These errors contain important information related to the sudden crash of the system. Some blue screen errors are more difficult to resolve than others, and WHEA Uncorrectable Error is one of them. Therefore, this article will guide you how to overcome this error and how to prevent it from happening in the future.

What is WHEA Uncorrectable error?

WHEA_UNCORRECTABLE_ERROR (Windows stopcode 0x0000124) is a hardware error. There are some common causes of WHEA_UNCORRECTABLE_ERROR (WUE) errors, most of which are directly related to your system’s hardware:

  • Bad hardware (hard drive, GPU, CPU, PSU, broken RAM, etc.)
  • Driver compatibility issues
  • Thermal and Voltage Problems (Overclocking and Voltage Changes)
  • The Windows system file or registry file is corrupt

Voltage problems are the common cause of this particular Windows error. The WUE error message and stopcode 0x0000124 tells us the nature of the error but you should see the dump file for more information. You can find the dump file (.DMP) in C:/Windows/Minidump and have the timestamp.

How to troubleshoot WHEA Uncorrectable Error


Before making any specific hardware changes, try running the Windows Check Disk from the Command Prompt. CHKDSK is a Windows system tool that verifies the file system and, with certain installations, fixes problems while running.

Type the cmd in the Start menu search bar, then right-click on the matching result and select Run as administrator. Alternatively, you can press, Windows Key + X, then select Command Prompt (Admin) from the menu. Next, type chkdsk / r and press Enter. This command will scan your system for errors and fix any problems during the process.

Check the system hardware

WHEA_UNCORRECTABLE_ERROR error is closely related to system hardware. Before proceeding with reinstalling the system and testing the memory, carefully check your system hardware. Check if the cooling system is working, is your RAM safe in its slots, and the CPU is loose, etc.

Reset Overclock the system

If you have overclocked your system to speed up, this may be the reason for the WHEA_UNCORRECTABLE_ERROR error. The easiest way to fix this problem is to reset the system BIOS and remove all the effects of overclocking.

You need to access the BIOS or UEFI by shutting down the system, then turning it back on and pressing the BIOS / UEFI menu access button (each computer will have different access keys, but usually F1, F2, F10, DEL and ESC).

Each manufacturer has different BIOS and UEFI settings, but the menu title is the same. After accessing the BIOS / UEFI menu, look for the Overclocking option. For most devices, you will see this option in the menu Advanced, Performance, Frequency, or Voltage.

Find this menu and reset the overclocking option. This reset puts your system back to its original state and can remedy the WHEA_UNCORRECTABLE_ERROR error in the process.

Reset BIOS / UEFI settings

If you remove the BIOS / UEFI overclocking setting, try resetting the entire BIOS. You can find the option to reset all BIOS settings or download the default BIOS settings in the BIOS menu. You can refer to the article 3 simple ways to reset the BIOS settings.

Update BIOS / UEFI settings

This process will vary depending on the motherboard manufacturer of the system. Some BIOS / UEFI settings can be automatically downloaded and updated using the desktop utility, but some manufacturers require users to download a BIOS update and manually flash the firmware.

If you do not know the information about your motherboard, you can download and run CPU-Z. Open the mainboard tab and look for the motherboard manufacturer and model. You can see the version and other BIOS information in this tab. After obtaining this information, search the Internet for BIOS update instructions or refer to the BIOS Update Guide article.

Check the system driver

Sometimes the driver has a bad effect on your system. However, today, you are less likely to encounter this problem because Windows 10 handles most of the driver updates. However, that does not mean it does not cause problems for your system. Fortunately, Windows 10 lists all the driver updates in the Windows Update section, so you can quickly find the cause of the problem.

Press Windows + I to open Settings, then select Update & Security> View update history. You can find any driver updates here. Now, type device manager in the Start menu search bar and select the most suitable one, see the list and check the error icon. If there is no problem, driver is not the cause of this problem.

You can use the third tool to update all your system drivers at the same time. Check out the list of tools for fixing major Windows problems.

Test your RAM with MemTest86

Windows has an integrated memory tester, called Windows Memory Diagnostics. However it often misses the problem, so we can use other tools like MemTest86.

MemTest86 is a stand-alone and free memory monitoring tool for x86 machines. You start MemTest86 from a USB flash drive (or bootable drive) and check the system RAM. This process will take several hours depending on the amount of RAM you install.

For a full MemTest86 experience, you should perform two complete test cycles, but according to most reports, MemTest86 can find serious RAM issues in a short time.

To create a bootable CD, load the image (ISO format), then save MemTest86 to the USB flash drive with the tool of your choice, then shut down the system. Restart the system while pressing the access button on the Boot Selection menu (usually F10, F11, DEL or ESC), then select the USB flash drive MemTest86 can boot, it will automatically check the memory. If you find an error, search the Internet for remedies.

Reset Windows 10

If none of the above measures work, you can use the Windows 10 Reset function to refresh the system. Windows 10 Reset replaces your system files with completely new files and will theoretically remove any issues related to the WHEA_UNCORRECTABLE_ERROR error while keeping most of your important files.

To do this, go to Settings> Update and Security> Recovery, then in Reset this PC, select Get started. After pressing this button, the system will reboot, so make sure to back up any important files before doing so. After reboot, you can select Keep my files or Remove everything.
