Windows has a long and beautiful (read: painful) history of blue-screen error messages. Affectionately known as the Blue Screen of Death, these error screens also contain important information regarding the sudden demise of your system.
Some Windows crash errors are more cryptic than others and therefore more difficult to troubleshoot. The WHEA Uncorrectable Error is one of those.
WHEA_UNCORRECTABLE_ERROR (Windows stopcode 0x0000124) is a hardware error. There are several common causes for a WHEA_UNCORRECTABLE_ERROR (we’ll abbreviate it as WUE), most of which directly relate to your system hardware:
- Corrupt hardware(Damaged hard drives, GPU, CPU, PSU, corrupt RAM, etc.)
- Driver compatibility issues
- Heat and voltage issues(Overclocking and voltage changes)
- Corrupt Windows system files or registry files
Although it isn’t always the source, voltage issues are a very common cause of this particular Windows error. The WUE message and 0x0000124 stopcode give us an indication as to the nature of the error, but a look at the error dump file will provide further information. Your error dump file (.DMP) is found at C:/Windows/Minidump and will have a timestamp.
Unfortunately, we cannot offer solutions for every issue, but the following fixes should alleviate your WHEA_UNCORRECTABLE_ERROR.
How to Fix the WHEA Uncorrectable Error
Remember the list of common system hardware issue that triggers WHEA_UNCORRECTABLE_ERROR? The following section expands on some of those hardware aspects and illustrates a few potential fixes.
Step 1: Run CHKDSK
First, before making any specific hardware alterations, 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 issues as it runs.
Type command prompt in your Start menu search bar, then right-click the best match and select Run as administrator. (Alternatively, press Windows Key + X, then select Command Prompt (Admin) from the menu.) Next, type chkdsk /r and press Enter. The command will scan your system for errors and fix any issues along the way.
Step 2: Check Your System Hardware
The WHEA_UNCORRECTABLE_ERROR closely relates to your system hardware. Before progressing with system resets and memory tests, physically double-check your system hardware.
Check if the cooling systems are fully functioning, your RAM is secure in its slots, and the CPU has mystifyingly not come loose, and so on.
Step 3: Reset System Overclocking
If you have overclocked your system in search of higher speeds, there is a chance you’ll run into the WHEA_UNCORRECTABLE_ERROR. The easiest way to cross this off the list is to reset your system BIOS and remove the effects of any overclocking.
You need to enter your system BIOS or UEFI menu. To do this, turn off your system. Next, turn your system back on, pressing your BIOS/UEFI menu access key (common keys include F1, F2, F10, DEL, and ESC).
BIOS and UEFI settings vary by manufacturer, but menu titles are usually similar. You are looking for an Overclocking option. For the most part, overclocking options are found under the Advanced, Performance, Frequency, or Voltage menu.
Find the menu and reset your overclocking options. Resetting will return your system to its out-of-box state—but could also remove WHEA_UNCORRECTABLE_ERROR in the process.
Step 4: Reset Your BIOS/UEFI Settings
If clearing your BIOS/UEFI overlock settings, try resetting your entire BIOS. Somewhere amongst the BIOS menu, there is an option to complete a full BIOS settings reset or load the default BIOS setup. Find the option and select it.
Step 5: Update Your BIOS/UEFI Settings
Again, this process varies heavily depending on your system’s motherboard manufacturer. Some BIOS/UEFI settings can automatically download and update using desktop utility. Other manufacturers require you to download the BIOS update and flash the firmware yourself.
Step 6: Check Your Drivers
Sometimes new drivers have an adverse effect on your system. In this day and age, it is becoming rarer as Windows 10 handles most driver updates. However, that doesn’t mean a dodgy driver cannot upset your system. Thankfully, Windows 10 lists any driver updates in the Windows Update section, so you can rapidly figure out where the issue stems from.
Press Windows Key + I to open the Settings panel, 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 select the best match. Head down the list and check for an error symbol. If there is nothing, your driver status is likely not the source of the issue.
