1. Run CHKDSK

Windows has an inbuilt way of checking and repairing disk-related problems, and it is advisable that before making any alterations to your hardware, you should first try and run the Windows Check Disk from the Command Prompt. The CHKDSK (check disk) is a Windows diagnostic tool that scans the computer’s data drive volumes, verifies their integrity, and where applicable, fixes any errors it encounters.

How to run CHKDSK on the Command Prompt

  1. On the Windows search box, type “Command Prompt“. Right-click and choose Run as administrator.
  2. Type “chkdsk/r” on the Command Prompt and hit Enter.

This command will scan your disks for errors and fix them along the way.

2. Reset System Overclocking

You might be experiencing the WHEA_UNCORRECTABLE_ERROR because you have overclocked your system, while in search of higher speeds. Overclocking supercharges the computer beyond the manufacturer’s intended limits and may cause the CPU to overheat and Windows to report various errors. If you have overclocked your PC, then you need to reset your PC’s BIOS. Here is how to do that:

  1. Turn off your computer and switch it on again, but this time pressing either of the following keys; F1, F2, DEL, and or ESC).
  2. This will bring your computer’s BIOS menu.
  3. The menu options differ depending on the computer’s manufacturer, but you will most likely find the overclocking settings under Advanced, Performance, voltage, or Frequency menus. You might have to navigate to a few of these before getting to the right one.
  4. Look for the Adjust CPU Ratio and Adjust CPU FSB Frequency settings. Set them to default. This will return your computer to a factory fresh state and in line with the manufacturers recommended clocking speeds.

3. Update Your PC’s Drivers

Drivers are system files that facilitate communication between the hardware and software components of your computer. If they are outdated, corrupt, or misconfigured, they could potentially cause all kinds of problems on your PC, including the WHEA_UNCORRECTABLE_ERROR. Therefore, as a precautionary measure, you need to make sure that all your drivers are up to date.

If you have a stable internet connection, the Search automatically for updated driver software option will be of great help to you. For those looking for alternatives to manual driver updates, third-party tools, such as Auslogics Driver Updater, offer features that can help in managing and updating drivers. As always, it’s recommended to ensure any software is from a trusted source and fits your specific needs.

A malfunctioning RAM can cause your computer to crash, freeze, slow down, or stop working altogether. That is why whenever your computer experiences any performance limiting issues like the WHEA_UNCORRECTABLE_ERROR, it is always advisable to diagnose the computers RAM for hardware changes, damage, or connection issues. This can be done using the inbuilt Windows Memory Diagnostics tool.

  3. Right-click on System and go to Find.
