What Is the WHEA Uncorrectable Error?

This error, also known as stop code WHEA_UNCORRECTABLE_ERROR or Windows code 0x0000124, is a hardware error. It indicates an issue with your computer’s hardware, such as your GPU, CPU, or RAM. The WHEA Uncorrectable Error message is also caused by voltage issues.

The most common causes for WHEA Uncorrectable Error are:

  • Malfunctioning hardware

Because this error is hard to diagnose accurately, we recommend that you take a look at the automatically generated error dump file (.DMP) found in C:/Windows/Minidump. Look for a file named after the date on which the error occurred and look for any details regarding what caused it. This will help you pinpoint the issue and make it easier to find a solution.

How to Fix WHEA Uncorrectable Error

You can begin correcting the mistake once you have determined its source. Several options exist for resolving the WHEA_UNCORRECTABLE_ERROR message, depending on its origin:

1] Run the CHKDSK Command

One reliable method for checking for and fixing hard disk issues is to run the CHKDSK command. Run this command to check your disk for faults and see if it can fix them. Here are the steps to run CHKDSK:

  1. Press the magnifying glass icon located on your taskbar to open the search box. The Windows key plus the S keyboard shortcut also gives you access to it.
  2. Fill out the search field using Command Prompt. Just right-click on it in the results and select Run as Administrator.
  3. When the User Account Control (UAC) prompts you, click Yes to open the program with administrator access.
  4. To run this command, type it in and hit Enter: check_drive chkdsk C: /f /r /x
  5. Wait for the scan to complete. When it finishes scanning your computer, check if you’re able to boot without seeing WHEA_UNCORRECTABLE_ERROR on startup.

2] Examine Your Hardware

Examining your hardware is an important step in troubleshooting computer issues. Check for loose connections and make sure that all components are securely fastened. Also, check for any obvious physical damage to the hardware.

To address the WHEA Uncorrectable Error, we suggest you assess if your cooling system is fully functional, each RAM stick is firmly in place, and the CPU hasn’t come undone. If you don’t know how to check your hardware, you can watch this video (and others like it from reliable sources) or ask for a professional to assist you.

If you notice that something is wrong with your hardware, you may have to replace it. If you own a Windows computer, you might be eligible for free Microsoft support and troubleshooting, too. Check your computer’s warranty status to find out if you qualify.

4] Stop Overclocking

When you overclock your computer’s CPU or graphics processing unit (GPU), you raise its clock speed beyond what it was originally designed for. Problems like crashes or other instability may result from this. If you’re having issues with your computer, you might want to consider removing any overclocking software.

If you used software such as MSI Afterburner to overclock your components, follow the appropriate guide to reverse the process. If you’ve been manually overclocking, then you’ll need to enter your system BIOS or UEFI menu and adjust the settings yourself.

  1. Reboot your computer.
  2. Before your system boots, access the BIOS menu by pressing the key indicated on the first screen. It can be one of these keys: Esc, Del, F2, F8, F10, or F12. If you see multiple keys listed, use the one assigned to open BIOS, setup, or BIOS menu.
  3. Navigate the interface and look for an option that says “Overclocking.” Usually, you’ll find this under the Advanced, Performance, Frequency, or Voltage menu, depending on your BIOS or UEFI manufacturer.
  4. Ensure that Overclocking is disabled. After turning this feature off, you can restart your device and see if this fixed the WHEA Uncorrectable Error.

5] Reset BIOS/UEFI Settings

Resetting the BIOS or UEFI settings can help resolve a variety of issues with your computer. This involves restoring the BIOS or UEFI settings to their default values.

Because every hardware is slightly different, there are many different ways to reset the BIOS/UEFI settings. Unfortunately, this means if you’re not familiar with the process, resetting your BIOS/UEFI should only be done in the presence of a qualified technician or an IT professional.

5] Update Your BIOS/UEFI

You can solve errors and improve your computer’s performance by updating your BIOS or UEFI. Make sure you follow the directions to the letter and get the most recent version from the manufacturer’s website.

  1. Keyboard shortcut: Windows + R. The Run utility will be launched.
  2. Press the Enter key after entering “cmd” without quotation marks. Pressing this button will open the Command Prompt program.
  3. After each line, press Enter to execute the command: press the key that follows every line of command to run the command.
    • systeminfo | findstr /I /c:bios
    • wmic bios get manufacturer, smbiosbiosversion
  4. You may determine the BIOS version with the aid of these commands. If you are not currently running the most recent version of your BIOS, use it to locate the most recent files needed for updating it.

6] Make Driver Updates

Your computer’s performance can be enhanced, and issues can be fixed by updating your drivers. It is critical to refer to the manufacturer’s website for the most recent version and pay close attention to the instructions. Certain drivers can also be updated via the Device Manager or Windows Update.

The Windows Update process for updating drivers

  1. Click the Start menu, then choose Settings. Alternatively, you can launch the Settings app by using the keyboard shortcut Win + I.
  2. Using the menu on the left, choose Windows Update and then select Advanced Options.
  3. After swiping down, select Optional Updates.
  4. Next, click the arrow icon to the right to expand the list of available Driver updates. After making your selections from among all the available driver updates, click the “Download & install” button.

The updates for Windows 11 will be downloaded and installed automatically. Upon completion of the installation, your computer might require a reboot. Following this, you should see if the WHEA Uncorrectable Error still appears while your device is starting up or is being used.

The best way to update drivers using Device Manager

  1. Make sure to press the Win + X keys on your keyboard. Get to the main menu, then choose “Device Manager.”
  2. After locating the device for which the driver has to be updated, right-click on it. From the context menu, choose “Update driver.”
  3. Ensure that “Search automatically for updated driver software” is checked.
  4. Windows will now search for the latest current driver for your device. If it detects one, it will download and install it without your intervention.

In order to apply the driver, your computer may need to be restarted. Another method is to search your machine for drivers. One great alternative is to go straight to the manufacturer’s website and install the driver by hand.

7] Launch MemTest86

MemTest86 is a helpful program for evaluating the memory on your computer. It can assist in identifying any faults that might be causing crashes or other issues by running a number of tests to check for any mistakes in the memory.

Note: You can run MemTest86 on any machine, regardless of the operating system installed, as it is a bootable software that operates separately from the OS.

  2. Choose the MemTest86 version (32-bit or 64-bit) that matches the architecture of your computer.
  3. Once the download is complete, use Rufus or another tool to burn the ISO file to a CD or USB disk.
  4. Set the BIOS/UEFI to boot from the CD/USB drive after restarting your machine. MemTest86 will launch automatically and start evaluating RAM. It will take a few minutes to finish the test.
  5. Should any faults be discovered, they will be shown on the screen. For more troubleshooting, take note of the issue specifics and get in touch with the RAM or computer manufacturer.
  6. If there are no faults discovered, your RAM is probably operating as it should. In this instance, the WHEA_UNCORRECTABLE_ERROR on your device is being caused by a separate part or problem. Utilize the techniques in this article to carry out further troubleshooting!
