In this post, I will tell you how to fix WHEA UNCORRECTABLE ERROR with or without logging in your PC. So, lend me your attention as we go through the process to get you out of this mess.


In Windows, BSOD or the Blue Screen Of Death is often caused due to internal issues. By internal issues, I am referring to corrupted/infected files, outdated driver or malfunctioning software. But the Whea Uncorrectable Error is caused due to hardware malfunctions.  In case of any faulty hardware, your machine faces issues starting Windows, inviting BSOD to your screen.

Well now we know the cause but who exactly is the culprit? Because even in a normal office machine, there is at least 5 hardware that can cause this problem.  Is it your hard disk, SSD, or maybe your ram, but I have two rams so which one is it? Worry not, it is actually really simple to tell. And fortunately for us, Windows comes pre-installed with tools to check these issues.

How to Fix Whea Uncorrectable Error

With the help of following fixes, we will help you detect your faulty hardware and see if it can be solved without exchanging a new one. Even if these fixes won’t solve the issue it will definitely help you detect the source of the error.

1. Check Hardware

So, before trying any of the fixes you need to make sure your hardware is functioning.

  1. Check if you ram is properly inserted. To ensure that, just take out your ram and insert it again. Don’t forget the click sound. You can also try switching the ram slots if you have extra.
  2.  Check if your cooling system is functional. While checking your CPU cooler also check that your CPU is properly placed at its position.
  3. Make sure that your Hard disks and SSD are properly plugged in with power supply and connected with your motherboard.

2. Boot your System

After doing so, you basically will have two scenarios. In the case of BSOD, you can either log in and access your Windows, or you can’t log in. Both of these issues are totally common. So, if you can access your Windows, skip this section. If you can’t, keep reading.

In order to make any changes, you will need to boot your system in safe mode.  Since you can’t log in to your Windows, you will need a bootable device. Once, you get one, follow-through-

  • Restart your PC and insert the bootable device while it is restarting.
  • Now, navigate to the Windows installation screen.


  • Instead of pressing Install, click on “Repair your Computer“.
  • Go to Troubleshoot -> Advanced options -> Startup Setting.

  • Here, press F4 to enable Safe Mode.

  • Now restart your PC.

3. Check Your Hard Disk

To ensure the source of the error, you can start checking with your Hard Disk.  In Microsoft Windows, there is a pre-installed tool called chkdsk. Chkdsk scans your hard disk and helps you find out the bad sectors on your hard disk and fix em’ if possible. To do so,

  • Start with opening command Prompt as admin. Press Windows + X and choose Command Prompt(admin).

open cmd as administrator

  • Now type in ” chkdsk /f ” and press Enter.

Use CMD to check for corrupted file

  • Wait for the tool to work, once completed, restart your system and check if the problem remains.

4. Check Memory

To check your memory or Ram, Windows also comes with a pre-installed tool called Windows Memory Diagnostics Tool. In case you don’t want to use a Windows tool, you can download a free tool called MemTest86.  But in this post, we will stick with the Windows tool. To access the Memory diagnostics tool, first-

  • Go to Control Panel and search Memory.

windows memory diagnostics

  • Then click on Administrative tool to begin the diagnostic.

  • This tool requires you to restart your PC. So, you can now either restart the computer and check the problem or schedule it for later.
  •  In case you get any error then your system has some RAM issues.

5. Reset Overclocking Setting Through BIOS

In order to reset your Overclocking Settings, you need to access Overclocking menu in your BIOS. If you have Overclocked your system through BIOS then you can revert back your changes through the same menu.

If somebody else overclocked your PC, then you need to do if yourself by accessing the BIOS menu.  Unfortunately, I can’t tell you the whole process as the BIOS varies as per their manufactures. So, you can either go to your manufacturer website to learn more or search it on youtube. But generally, you can find the overclocking menu under Advanced, frequency or Performance menu.

Once, you have reset your overclocking settings to default, restart your PC.

6. Reset your BIOS

You can also reset your BIOS, in case you cant access your Overclocking menu.

  • Restart your computer to access BIOS, you can do so by pressing F1, F2, ESC, Del or F10, depending on your motherboard.
  • Now search for options like “Reset Default“, “Setup Default“, “Factory Default“.
  • Once you press Enter, you will get a confirmation box. Click on Yes to confirm.
  • Now, restart your PC and you are good to go.

7. Update your BIOS

If it is a compatibility issue or you have installed a new hardware/ Windows, then updating your BIOS might help. To update your BIOS you will first need to know your motherboard’s model number with its manufactures name. You can do it by

  •  Opening your desktop as it is written on your motherboard.
  • Downloading CPU-Z as it can tell you directly.


Once you have your motherboard’s model number and manufacturers name, you can go to the manufactures Website to download updates.

8. Check Your System Drivers

As mentioned above, the Whea Uncorrectable Error is caused due to hardware issues, but it might not be the hardware causing the problems. The given error can also be caused due to incompatible drivers or corrupted drivers file. The best way to solve this problem is by updating them. You can do that by updating your Windows through Windows update or individually updating your Drivers.

To do so,

  • Open Command Prompt as admin, just like before.
  • Now, type in “eventvwr” and press Enter.

  • Go to Windows Logs -> System.

  • Here, every task at a critical level can cause this problem. By clicking on Source, you can find the source and manually download the drivers.
