Fixing System Thread Exception not handled (Fixed)

The System Thread Exception Not Handled is a common error that you can see on a Windows Computer. The error occurs when the threads(small programs) that run some critical windows services fail.

The error is mainly reported by the users of the new Windows OS i.e. Windows 8 to 10. Some users get 15 seconds of use on a computer and then get this error. Other users have reported the error immediately after the windows start.

The system will reboot once you see this error and this will make it impossible to use the computer. You also get a Blue Screen of Death (BSOD) along with the error. Today we will be talking about this issue in windows and see the possible solutions for this problem.

System Thread Exception not handled

What is the reason for the error?

The System Thread Exception Not Handled error is mainly caused because of serious driver malfunction. If you have an outdated graphics or wi-fi driver, audio driver, or any driver that is just incompatible, windows will boot your system to display this blue screen.

Driver problem can cause errors like Audio Service is Not Running so I recommend you to fix drivers.

In addition to outdated drivers, overlocking your GPU or some thermal performance issue can also be the reason for the BSOD. If this is the case, the BSOD will occur only once or twice. But if the error is occurring repeatedly then, you’d need to do something to fix this issue.

The one-stop solution to the System Thread Exception Not Handled problem is to fix all the drivers. The keyword here is ALL so, you need to fix the drivers for display, sound, wi-fi, and everything else.

  • Just go to the Windows computer and browse to Device Manager.
  • Now check for the corrupted drivers. When you detect that the driver isn’t working just uninstall it.
  • After it is uninstalled, reinstall it. This will fix your problem.

update drivers

You can also upgrade the driver to the latest version to fix the issue.

Reset your PC

This is probably a last-ditch effort if fixing the drivers doesn’t help you out with the problem. You can follow the instructions given below to reset your PC and fix any software problem in it.

  • Just go to the settings first and select the “Update and Security” option.
  • Click on the recovery tab on the left side of the menu.
  • Windows will give you three options now:
    Reset the PC, Go to an earlier build, and Advanced Startup.
  • Click on the Reset the PC option for resetting it. The advanced startup option lets you boot from a USB Recovery drive. If you have saved the earlier “image” of a window like a backup then you can “go to an earlier build” by clicking the third option. For now, we just need to reset the PC so, focus!
  • Now, go to the¬† get started tab under Reset this PC and click either “Keep my files” or “Remove Everything.” Select what you need the system to do. It doesn’t matter what you select really though, your settings will revert back to default and apps will be uninstalled.
  • You still have two options, you can either “remove your files” or “remove files and clean the drive’, you get this option when you select ‘remove everything’ in the prior step. Cleaning the whole drive will take longer and it will erase all your files. If you will be using the computer again then, select the ‘just remove my files’ option.
  • Click on the Next tab and then click on the Reset button when the System prompts you. This could take anywhere from 20 to 30 minutes so, you can just relax for that time.
  • After the system has been reset, follow the on-screen commands, and there you go, a refreshed system!

Format with the Optical Drive or USB Device

If you can’t get into your Windows Operating system and are stuck on the blue screen then, you need to reformat windows. You can do it in two ways, you can either insert the optical drive and boot from there or you can use a USB device to format the windows. For formatting the windows, follow the steps given below:

  • Get a Windows 10 DVD or a USB Device that has windows 10 image burned into it.
  • Click on the power button on the computer and while it is being booted hit on the Del key on the keyboard to enter the boot screen. Remember, different PCs have different ways for accessing the boot screen. The keys can be DEL, F10, F11, or F12. Find the key by the process of elimination.
  • When you are in the boot screen, simply select the boot device. If you have a DVD, boot from CD Drive, and if you have inserted the USB device, boot from there.
  • Wait a bit till the system boots from your selected device. Once the boot is complete and you are in the Windows Installation screen, just follow the onscreen commands and you should be able to reinstall windows.
  • Windows is generally installed in the C drive and you need to format this drive. Never format other drives though, you can lose your data if you do it.
  • The whole installation process will take around 30 to 50 minutes depending on your system. So, have patience!
