Possible Solution 2. Get the Latest Updates with Windows Update

Possible Solution 3. Disable Overclocking CPU or GPU

CPUs and GPUs these days are able to overclock to their highest extent in search of higher speeds. Overclocking the CPU results in processor overheating which can also be the cause for WHEA uncorrectable error. Besides this error, overclocking can lead to various other stop codes. Hence, a simple measure to fix WHEA_Uncorrectable_Erroris to disable overclocking in BIOS.

If you did this, it’s best that you disable it on your PC. To reset or disable overclocking, head over to your PC’s BIOS or UEFI Menu. You can enter your system’s BIOS menu by turning off your PC and pressing BIOS/UEFI menu access keys (like F1F2F10DELESC). These keys might differ from one manufacturer to another one.

Once you enter the BIOS, look for the Overclocking option. You might usually find them under the Performance, System, Advanced, Frequency or Voltage options.

Possible Solution 4. Check For Drivers Errors

Another common cause for the WHEA_Uncorrectable_Error can be incompatible drivers. To check for driver errors, you need to open up the Device Manager. To open Device Manager, click on Start and type “Device Manager”, then hit Enter.

Possible Solution 5. Run CHKDSK

If you fixed possible hardware issues and still couldn’t get rid of the WHEA_Uncorrectable_Error, then it’s recommended to check for issues on the hard disk’s side. Windows comes with built in troubleshooting tool known as Check Disk Utility (CHKDSK). This tool essentially scans system files for errors and repairs files if possible. The same tool can also be used to identify bad sectors on a hard drive. 
To run CHKDSK,

  1. Click on search box and type ” cmd ” .
  2. Right click on cmd.exe and choose run as administrator.
  3. Now in the command prompt box type CHKDSK x : / f / r and Press Enter (x stands for the respective drive)

Possible Solution 6. Reset BIOS to factory settings

If you have made any other changes to your BIOS besides overclocking (which we described in a previous solution), you might have accidentally messed up your hard drive settings and caused the WHEA UNCORRECTABLE ERROR error.

Clearing BIOS might not work for everyone, but resetting the BIOS can fix the WHEA Uncorrectable Error.

To reset your BIOS, head over to the BIOS menu as mentioned in the 2nd option. After you enter the BIOS menu, look for options like Reset BIOS settings, Restore Defaults or something similar to them. Depending on the manufacturer, you might see different options. This might possibly fix the 0x0000124 error on your Windows 10 PC.

After resetting your BIOS, you might want to set the date and time accurately. It is because the BIOS reset completely resets the system’s clock settings.

Possible Solution 7. Troubleshoot the driver issues in Safe Mode

Reboot the system -> Enter the Safe Mode (Press F8 or Shift+F8) 

If it does not work ask for the key from your manufacturer.   

Select Troubleshot -> Advanced options -> Startup Settings -> Restart. 

After that, press Windows key + R in the Safe Mode, then just type devmgmt.msc and press enter key to open the Device Manager of the system.   

The yellow or red marked sign should be updated and finally restart the system to see whether the whea error exists or not.        

Possible Solution 8. Fix BCD Error

Becuase you are receiving the WHEA uncorrectable error upon boot up then it could be worth investigating fixing the Windows boot configuration data (BCD). If the Windows boot configuration data (BCD) store is missing, corrupted or improperly configured various errors will appear on boot up. To fix and rebuild the BCD, follow the steps below:
