Reset the system overclock

If you have overclocked the system to speed up, this may be the cause of the WHEA_UNCORRECTABLE_ERROR error. The easiest way to fix this problem is to reset the system BIOS and remove all overclocking effects.

You need to access BIOS or UEFI by turning off the system, then turn on and press BIOS / UEFI menu access key (each computer will have different access keys, but usually F1, F2, F10 keys, DEL and ESC).

Each manufacturer installs different BIOS and UEFI, but the menu title is similar. After accessing the BIOS / UEFI menu, find the Overclocking option. For most devices, you will see this option in the Advanced menu , Performance, Frequency , or Voltage .

Find this menu and reset the overclocking option. This reset brings your system to its original state and can fix WHEA_UNCORRECTABLE_ERROR error in this process.

Reset BIOS / UEFI settings

If clearing the BIOS / UEFI overclocking settings, try resetting the entire BIOS. You can find the option to reset all BIOS settings or download the default BIOS settings in the BIOS menu. You can refer to the article 3 simple ways to reset BIOS settings.

Update BIOS / UEFI settings

This process will vary depending on the system's motherboard manufacturer. Some BIOS / UEFI settings can automatically download and update using the desktop utility, but some manufacturers require users to download BIOS updates and flash the firmware themselves.

If you don't know the information on the motherboard on your device, you can download and run CPU-Z. Open the Mainboard tab and find the manufacturer and motherboard model. You can see the version and other BIOS information in this tab. After obtaining this information, search the Internet for BIOS update instructions or refer to the BIOS Upgrade Instructions article.

Check the system driver

Sometimes drivers have a bad effect on your system. However, today you are less likely to encounter this problem because Windows 10 handles most of the driver updates. However, that does not mean that it does not cause problems for your system. Fortunately, Windows 10 lists all the driver updates in the Windows Update section, so you can quickly find out the cause of the problem.

Press Windows + I key to open Settings , 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, view the list and check the error icon. If there is no problem, the driver is not the cause of this problem.

Check your RAM with MemTest86

Windows has an integrated memory checker, called Windows Memory Diagnostic. However, it often misses problems, so we can use other tools like MemTest86.

MemTest86 is a free and independent memory testing tool for x86 machines. You start MemTest86 from a USB flash drive (or a bootable drive) and check the system RAM. This test process will take several hours depending on the amount of RAM you install.

For a full MemTest86 experience, you should perform two complete tests, but according to most reports, MemTest86 can find serious RAM problems in a short time.

To create a bootable CD, download the image (ISO format), then write MemTest86 to the USB flash drive using the tool of your choice, then turn off the system. Reboot the system while pressing the button to access the Boot Selection menu (usually F10, F11, DEL or ESC), then select the MemTest86 USB flash drive that can boot, it will automatically check memory. If an error is found, search the Internet for a remedy.
