  1. Enter the task name in CMD into the text field.
  2. Click ‘OK.’
  3. Right-click on Command Prompt in the list of tasks in Task Manager and select ‘Run as Administrator.’
  4. Once CMD opens up, type bcdedit /set nx AlwaysOff.
  5. Click ‘Enter’ when finished typing out this command line.
  6. Restart your computer to complete this process and continue using Windows without errors!

Root Causes of the WHEA Uncorrectable Error

Root Causes of the WHEA Uncorrectable Error

A few different things could be causing the WHEA Uncorrectable Error on your Windows computer. It could be a problem with your hardware, BIOS, or drivers. It’s also possible that there’s a problem with the way your computer is configured. 

If you’re not sure what the root cause of the problem is, you can try troubleshooting by looking at each of these potential causes.

Start with the easiest one and work your way up until you find a solution. If none of these work for you, then contact Microsoft Support. They will have more ideas on fixing the issue if you explain what happens when you get the error message and how often it occurs. 

Start with checking to see if your computer is compatible with the software you are trying to use. Next, check your BIOS settings. Sometimes BIOS settings need to be updated after installing new hardware or other settings to take effect properly. Ensure all the latest updates and all the necessary device drivers have been installed onto your PC. 

You may need additional programs for this to happen, so download them from their website or make sure they come pre-installed onto your computer before updating anything else. Finally, ensure everything is set up correctly in Windows, such as permissions and file associations.

How to Fix WHEA Uncorrectable Error

The WHEA Uncorrectable error can be fixed in several ways, depending on the cause. You’ll need to replace the affected component if you’re getting the error because of a hardware issue.

If a driver issue causes the error, you can try updating or reinstalling the driver. If there’s a problem with your BIOS, you may need to update it.

On top of that, if a software issue causes the error, you can try repairing or reinstalling Windows. You could also run Memtest86+ and stress test your system to ensure everything is functioning properly. Finally, you can look up potential fixes for the WHEA Uncorrectable error online. 

In most cases, a simple Google search will yield many different answers. These articles offer suggestions like resetting your BIOS to default settings, checking whether an incompatible device is causing problems, or ensuring that your motherboard has good ventilation.

Follow Microsoft’s instructions for creating a bootable USB drive from another computer. One of these solutions was best instead of simply restarting the computer without changing anything. 

Follow the steps below to clarify what you should do if you ever encounter the WHEA Uncorrectable error on Windows.

Update BIOS

If you’re getting the WHEA Uncorrectable Error, you should first update your BIOS. This is because an outdated BIOS can cause the error. A BIOS (Basic Input Output System) is software embedded in a motherboard that’s responsible for enabling your computer to start up. Updating the BIOS might resolve the issue, so updating it before anything else is worth a try. 

A few ways to check if there are any new updates available are: 

  • Checking the manufacturer’s website.
  • Running BIOS Update Utility from within the computer’s operating system or installing a third-party program like ASUS Live Update Utility or HP Support Assistant.
  • The BIOS might notify you of new updates after restarting your computer and booting into the OS.
  • Plug your PC into an internet connection and look at the router’s list of connected devices, which should include the computer name with a message saying, “There are firmware upgrades.”
  • Contacting customer support at your PC manufacturer or calling them and asking about available updates – Downloading a third-party tool like CPU-Z.
  • Downloading and running the Intel Processor Identification Utility.
  • Download and run the Diagnostic Tool to find out what version your BIOS is, and contact customer service for more information about updated versions.

Check for Rogue Programs/Viruses

In case of BIOS Update does not work for your PC or Laptop, then follow the below steps:

  • Run a full scan using antivirus/anti-malware software. 
  • Certain viruses can cause blue screens, black screens, or even loops where the screen continuously flickers on and off – these are all tell-tale signs of malicious activity occurring in the background without detection. 
  • You may also want to reboot into Safe Mode with Networking to run scans since malware doesn’t usually run when Windows is not active.
  • After rebooting in Safe Mode, press ‘F8‘ multiple times until a menu pops up; use the arrow keys to select Safe Mode with Networking and press ‘Enter‘ to continue. Then use the steps listed above for scanning.
  • Once done, exit the Safe Mode with the Networking environment by pressing ‘Ctrl+Alt+Delete.’
  • Then press ‘Enter‘ again to log into your normal account and reboot normally. If the problem persists, refer to step 3 below.

Run Hardware Diagnostics

If you’re still getting the WHEA Uncorrectable Error after following the first two steps, there’s likely a hardware issue. To test this, you can run hardware diagnostics. 

  • Press the ‘Windows Key + X + A‘ and type in ‘msinfo32.’ Click the Boot tab and check for errors (hint: use CTRL+F to search). 
Hardware Diagnostics
  • Once you find an error, go through the troubleshooting process for that specific device.
  • You’ll have to Google or YouTube instructions on how to replace your specific component. You may also want to consult a technician if you’re unsure what to do next. 
  • For example, we’ve seen many people change their RAM only to realize they needed to change their graphics card
  • These are just examples of problems that could be causing your WHEA Uncorrectable Error.

Check RAM

If you’re getting the WHEA Uncorrectable Error, it’s likely because there’s something wrong with your RAM. You should run a memory test to see if your RAM is causing the problem. You can use free tools like Memtest86+ or Intel Memory Diagnostic Tool


If the tests come back clean, there may be an issue with your graphics card driver, and you should contact support for that specific hardware vendor or manufacturer. 

However, if these tests show errors in your system memory, you must replace those parts before continuing. When people get the WHEA Uncorrectable Error, they think their computer is broken and buy a new one. When in reality, all they needed was some new RAM!

Disable Fast Boot Mode

  • Press the ‘Windows logo key + R‘ simultaneously to open the Run dialog box.
  • Type’ Control‘ in the Run dialog box and press ‘Enter‘ to open the Control Panel.
  •  Select Hardware and Sound > Power Options > System Settings in the Control Panel.
  •  Under Shutdown settings, clear the Turn on fast start-up (recommended) check box and click Save changes.
Power Options
  • Close the Control Panel and restart your computer for the changes.
  • After your computer restarts, press the ‘Windows logo key + R‘ to open the Run dialog box again.
  • Type ‘MSConfig‘ in the Run dialog box and press ‘Enter‘ to open System Configuration. 
  • Click the Boot tab in the System Configuration window and disable all services except for Safe boot by clicking the corresponding check boxes beside them.
System Configuration
  • Click the ‘Apply‘ button to save changes and close the System Configuration window
  • Restart your computer after completing these steps successfully to confirm that there are no WHEA errors. 
  • Check if any updates are available from Windows Update if you want to keep your system up-to-date with the latest security patches and software fixes. 
  • If there is no update available, or if updating does not help fix the issue, contact Customer Support. They will be happy to help! 
  • Enjoy hassle-free computing with WHEA errors fixed.

Disable Overclocking

If you’ve overclocked your CPU, GPU, or RAM, try resetting them to their default speeds. Overclocking can cause the WHEA_UNCORRECTABLE_ERROR if your components are pushed too far beyond their limits. To reset your CPU: 

  • Open the BIOS menu. This is usually done by pressing a key during bootups, such as F2, Esc, or Del.
  • Find the CPU Settings or Overclock menu. 
  • Reset all the values to their defaults. 
  • Save and exit settings and reboot your computer (restart should suffice). 
  • Repeat Steps 3-5 for any other overclock settings in your BIOS menu (such as Memory Clock, Voltage Control, etc.). 
  • After rebooting, rerun Memtest86+ overnight and ensure no errors are found before trying out Step 7 in this guide.

Remove Duplicate Network Adapters

If you have multiple network adapters installed on your computer, that could be causing the WHEA uncorrectable error. To remove duplicate adapters, follow these steps:

  • Open Device Manager.
  • Expand the Network Adapters section.
  • Right-click each adapter and select Uninstall device.
  • Restart your computer and check if the problem is fixed.
Device Manager

Clean up your Hard Drive Space

Your computer may be running low on hard drive space, which can lead to all sorts of problems. Start uninstalling programs you don’t use to clean up your hard drive space.

Then, delete any files you don’t need, such as temporary files, caches, and cookies. You can also use a tool like CCleaner to automate the process. Finally, consider upgrading to a larger hard drive if you continue to have space issues.


The WHEA Uncorrectable error is a severe problem that can cause your computer to crash. However, you can do a few things to try and fix it. First, make sure you have the latest drivers installed for your hardware. You can try resetting your BIOS or installing Windows clean if that doesn’t work. If all else fails, you may need your manufacturer for Support Assistance.
