What is the WHEA Uncorrectable error?

WHEA_UNCORRECTABLE_ERROR (Windows stopcode 0x0000124) is a hardware failure. There are several common causes of the WHEA_UNCORRECTABLE_ERROR (abbreviated WUE) error, most directly related to your system hardware:

  • Damaged hardware (damaged hard drive, GPU, CPU, PSU, RAM, etc.)
  • Driver compatibility issues
  • Heat and voltage issues (Overclocking and voltage changes)
  • Corrupt Windows system files or registry files

Voltage issues are a common cause of this particular Windows error. The WUE and stopcode 0x0000124 error messages tell us the nature of the error, but you should look at the dump file for more information. You can find dump file (.DMP) in C: / Windows / Minidump and have timestamp.

How to fix the WHEA Uncorrectable Error


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

Type command prompt in the Start menu search bar, then right-click the match 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 along the way.

Check the system hardware

The WHEA_UNCORRECTABLE_ERROR error is closely related to the system hardware. Before proceeding to reinstall your system and test your memory, double-check your system hardware. Check if the cooling system is working, your RAM is safe in its slots, and the CPU is loose, etc.

Re-insert the memory (RAM)

Memory reassembly is the process of removing the memory module from the DIMM slots and placing them back in the correct position. Follow these steps:

Step 1 . Locate the pin or screw on the protective plate.

Step 2 . Pull the latch / remove the screw to remove the guard and set aside.

Step 3 . Locate memory. Gently release the clips holding the RAM in place. Do this for all available memory modules.

Step 4 . Carefully re-insert each memory module into the DIMM slots on the motherboard.

Step 5 . Press firmly on each side of the memory module until the retention clips snap into place.

Once the memory is securely re-inserted into the DIMM slots, you can now power on your computer to check and see if reinstalling the RAM solves the problem. If the PC boots up with no problem, you have successfully fixed the problem.

Reset overclocking system

If you have overclocked your system to increase the speed, this is probably the cause of 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 BIOS or UEFI by shutting down the system, then turning it back on and pressing the BIOS / UEFI menu access key (each computer will have a different access key, but usually F1, F2, F10, DEL and ESC).

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

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

Reset BIOS / UEFI settings

If you clear your BIOS / UEFI overclocking settings, try a full BIOS reset. You can find the option to reset the entire BIOS settings or load the default BIOS settings in the BIOS menu. You can refer to the article 3 simple ways to reset BIOS settings.

Update BIOS / UEFI settings

This process will vary depending on the manufacturer of your system motherboard. Some BIOS / UEFI settings can automatically download and update using the desktop utility, however some manufacturers require users to download BIOS update and flash the firmware themselves.

If you don’t know the motherboard information on your machine, you can download and run CPU-Z. Open the Mainboard tab and find your motherboard manufacturer and model. You can see the BIOS version and other information on this tab. After obtaining these information, search the Internet for BIOS update instructions or refer to BIOS Upgrade Instructions article.

Check the system driver

Sometimes drivers have a bad effect on your system. However, these problems are less common these days as Windows 10 handles most driver updates. However, that doesn’t mean it’s not crashing your system. Fortunately, Windows 10 lists all driver updates in the Windows Update section, so you can quickly find the cause of the problem.

Press Windows key + 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 choose the best match, look at the list and check for the error icon. If there is no problem, the driver is not the cause of the problem.

You can use the third tool to update all system drivers at once. Check out our list of tools to fix major Windows problems.

Test your RAM with MemTest86

Windows has an integrated memory checker called Windows Memory Diagnostic. However it often overlooks the problems so we can use another tool like MemTest86.

MemTest86 is a free and standalone memory testing tool for x86 machines. Boot MemTest86 from a USB flash drive (or bootable drive) and check the system RAM. This test will take a few hours depending on how much RAM you have installed.

For the full MemTest86 experience you should go through two complete test cycles, however according to most reports MemTest86 can find serious RAM problems in no time.

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