Fix - WHEA UNCORRECTABLE BSOD Error 0x00000124 in Windows 10

Unlike previous operating systems by Microsoft, Windows 10 users now enjoy new build versions and their unique features. The company releases security patches every month to fix any issues. Despite all this, Windows 10 is more susceptible to errors and bugs and Blue Screen is one of them. Today, in this post, we discuss one such system crash bugcheck- WHEA UNCORRECTABLE BSOD Error 0x00000124, the triggering reasons, and possible ways to fix it. WHEA stands for “Windows Hardware Error Architecture” which implies fatal error owing to either internal or external physical components. The hardware failures include RAM, hard-drive, processor, graphics, cooling system, etc.

The software conflict like driver issues, system programs, BIOS settings, or pending updates are a few reasons that may cause the WHEA UNCORRECTABLE Error. To resolve this system crash bugcheck, perform SFC scan, update the driver, install the latest patches, Run Blue screen troubleshooter, etc. If none of these fixes work, look for any memory conflicts or perform a few changes under the BIOS. In case the error persists even after this, there might be a hardware issue. This requires expertise solving, so we suggest visiting the nearest service center. Let’s explore the software related workarounds in detail –

How to solve WHEA_UNCORRECTABLE_ERROR 0x00000124

To fix the WHEA UNCORRECTABLE BSOD ERROR 0x00000124, use the following workarounds –

Note: Since this is a blue screen of death error, you can’t access the login screen normally. So, you must enter the Safe Mode with networking then only apply the below fixes.

1] Unplug Peripheral devices

The peripheral devices play a significant role in our day-to-day activities. However, after getting a BSOD error, you should first remove all of the secondary devices and see whether it does solve the underlying cause. If you have recently installed any graphic card or network devices, this may also cause the error 0x00000124 due to some compatibility issues. If this is indeed the case, unplugging these devices may solve this system crash error.

Note: Make sure to plug in the devices one by one to identify the corrupt one. In case, the error still exists, move to the next solution.

2] Scan PC for missing/damaged system files

Many a time, if you didn’t perform Windows 10 update regularly can also result in such Stop errors. This occurs because system files start missing or simply become corrupt over a while. Moreover, sudden power fluctuation (pretty common these days) can also cause this kernel error. To get rid of this issue, you should scan the entire PC for possible obsolete system files using SFC utility. This tool not only finds the damaged core files but also repair them instantly.

On the elevated command prompt, type sfc/scannow and press the Enter key.
The file scanning/repairing starts immediately afterward, so wait accordingly.

Once over, Reboot your PC and check whether you can boot into Windows 10 normally or not.

3] Update Device Drivers

The presence of outdated device drivers can also lead to the blue screen of death errors. Therefore, make a practice of checking and upgrading obsolete software drivers. Here’s how to proceed –

Hold down the Windows key and press X to launch the Power Menu.
From the list, click Device Manager. Next, expand all the categories separately and check if there is a yellow exclamation mark.
