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.

Repair file system and MBR
You can fix the file system and MBR to correct the Whea_Uncorrectable_Error error. Since you cannot boot into your system, you need to start your computer using the Windows 10/8/7 installation DVD. If not, you need to create one using the Windows Media Creation Tool. Then, follow the steps to fix MBR in Windows 10 using CMD.
Step 1 . Boot from original installation DVD (or recovery USB)
Step 2 . At the Welcome screen, click Repair your computer in the lower left corner.
Step 3 . Select Troubleshoot> Advanced Options> Command Prompt .
Step 4 . Once the Command Prompt loads, enter the following commands and press Enter after each one:
Bootrec.exe/fixmbr Bootrec.exe/fixboot Bootrec.exe/rebuildbcd
Step 5 . When done, exit the Command Prompt window, eject the DVD and reboot the computer.
You can also fix the BCD error to resolve the WHEA Uncorrectable problem. Enter the Command Prompt as instructed above and follow the steps below.
Step 1 . Enter each command line and press Enter each time:
ren BCD BCD.old bcdboot C:Windows /1 en-us /s G: /f ALL
Note : C: is the drive where Windows 10 / 8.1 / 8 is installed.
Step 2 . Enter exit in Command Prompt when the process is complete and then reboot your PC.
Fix the problem with the installation disc
If the computer still won’t boot, you should create a Windows 10/8/7 repair disc and fix your system errors. To create a repair disc, you need a healthy, bootable computer.
Step 1 . Insert the CD / DVD into the connected DVD-ROM or external DVD drive.
Step 2 . Click “Control Panel” on the computer screen, then click “Backup and Restore (Windows 7)”.
Step 3 . Click “Create a system repair disc” from the left column to open the create repair disc window. Follow the onscreen instructions to create a system repair disc.
Step 4 . Connect the disk to the PC with the Whea_Uncorrectable_Error error and reboot to boot from the DVD. You may have to change the boot settings in your BIOS, if booting from CD / DVD is not enabled.
Step 5 . On the “Install Windows” screen , make the appropriate choices for the language, time, and keyboard, then click “Next”.
Step 6 . On the next screen, click “Repair Your Computer” . Don’t click “Install now”. Then, click “Next” and choose “Startup Repair” or whatever option you want to apply.
After these steps, you should be able to boot into your computer as you normally would. Then check to see if you have resolved the WHEA Uncorrectable error. If the error persists, you can restore the system with a repair disc.
As mentioned in step 6, you have many options. If you still get the error, select “System Restore” and follow the on-screen steps.
System Restore: Restore Windows to an earlier point in time. Select this option if Windows 10/8/7 boots up, but something has changed since the last install or update. You will choose a restore point based on date and time (starting with the most recent). You may lose recent program changes, but not data.
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 brand new ones and should theoretically eliminate 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 under Reset this PC , select Get started . After pressing this button, the system will reboot, so make sure to back up any important files before proceeding. After the reboot, you can choose either Keep my files or Remove everything .
