Solution 1 – Update your drivers

Blue Screen of Death errors are often caused by incompatible or outdated drivers, therefore it’s crucial that you update drivers as often as you can. In order for Windows 10 to recognize and use your hardware, your drivers have to be up to date, and if that’s not the case, your PC will crash while giving you the MACHINE CHECK EXCEPTION error.

Easiest way to fix this issue is to update your drivers, and you can download all the necessary drivers from your hardware manufacturer’s website. Users confirmed that updating their drivers fixed the problem for them, so be sure to try that.

Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically. Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.

Solution 2 – Run the BSOD Troubleshooter 

The next thing we’re going to try here is running Windows 10‘s built-in troubleshooting tool. This tool can be used for dealing with all sorts of issues, including the BSOD problems. So, it could be useful when dealing with the MACHINE CHECK EXCEPTION error, as well.

Here’s how to run Windows 10‘s troubleshooting tool:

Solution 3 – Run the SFC scan

The next troubleshooter we’re going to try is running the SFC scan. This is a command-line tool that repairs corrupt system files, which can resolve BSOD issues.

Here’s how to run the SFC scan in Windows 10:

And the third command-line troubleshooting tool we’re going to try here is DISM. Deployment Image Servicing and Management (DISM), as its name says, re-deploys the system image, which can lead to resolving BSOD issues, like MACHINE CHECK EXCEPTION.

We’ll walk you through both standard and the procedure that utilizes the installation media below:

  • Standard way

  6. After the procedure is finished, restart your computer.

Solution 5 – Check the hard drive

If there’s something wrong with your hard drive, BSOD issues are to be expected. So, go ahead an run the chkdsk command in order to scan your hard drive, and fix potential issues.

Here’s how to run the chkdsk command in Windows 10:

  2. Choose Troubleshoot > Advanced Options.
  3. Select Command Prompt from the list of options.

    • bootrec.exe /rebuildbcd
    • bootrec.exe /fixmbr
    • bootrec.exe /fixboot
  5. Some users are also suggesting that you need to run additional chkdsk commands as well. To perform these commands, you need to know drive letters for all your hard drive partitions. In Command Prompt you should enter the following (but remember to use the letters that match your hard drive partitions on your PC):
    • chkdsk /r c:
    • chkdsk /r d:

    This is just our example, so keep in mind that you have to perform chkdsk command for every hard drive partition that you have.

  6. Restart your computer and check if the issue is resolved.

Solution 6 – Uninstall your graphics card driver

  2. Start the tool and follow the instructions.

After removing the display driver you just have to visit your graphic card manufacturer’s website and download the drivers for your graphic card.
