Solution: 2.1 Uninstall recent updates.

As I have mentioned before, “system thread exception not handled” error occurs, when updates get corrupted. In Windows 10, installation process of update start automatically. And, there isn’t any option to stop auto updates by Microsoft. You need to tweak few Windows settings, to stop these auto updates. Although, you can schedule some Windows updates. But, If the update is important then you can’t schedule it.

So, if Windows has installed any updates recently, then you should uninstall that update. And, if you’re stuck in the boot loop, then the safe mode is the only way to do that.

Safe mode is also known as the diagnostic mode. It only allows Windows to run essential program and services. Safe mode doesn’t load most of the driver, that’s why when you run your Computer in safe mode. Not an error occurs, and this indicates that problem is with the driver.

Though, there are multiple ways to boot system in safe mode. But in this error Computer get stuck into a boot loop. So, we are using startup method here.

And, if it does then right click on it and uninstall the update. After uninstalling recently updates, shut down the computer and start it in normal mode.

Solution: 2.2 Roll Back Display Driver.

According to many Windows user, “system thread exception not handled” error occur due to faulty display or graphics driver. So, if you have installed any graphics driver recently, then you need to uninstall it. In Windows, you can roll back device driver to the previous version. So, instead of uninstalling the driver completely, we are going to roll back driver.

To do this, you need to boot your system in safe mode. In safe mode, Windows uses standard VGA graphics mode. So, you will not face “system_thread_exception_not_handled” error.

Solution: 3 Change Driver File Name.

“system thread exception not handled” error comes with a file name, which is occurring this error. File Name could be similar to iaisp64.sys, atikmdag.sys, nvlddmkm.sys or can be different. You can fix this error, by changing that file name. So, Windows OS will not able to detect that faulty file.

Before starting this process, first, note down file name from BSOD error screen.

Step: 2 Now, type the following command and press enter to change default directory to directory of driver folder.

cd c:\windows\system32\drivers

Step: 3 To rename the file name use the following command. I am giving just an example, you need to enter an actual file name in this command.

ren DriverFileName.sys DriverFileName.old (Replace DriverFileName with the file name, which is causing this BSOD error.)Rename Driver File Name

After renaming the file, now you can start Windows normally. And, you will not face any error, after trying this solution.

Solution: 4 Install or Update Driver.

After renaming file name, hopefully, your problem gets resolved. But to fix this error permanently, you need to update your graphics driver. To update graphics driver, go to the manufacturer site and select compatible version. For example, On my laptop, I am using “Nvidia GeForce 820M“. So, by going to Nvidia site, I can get latest driver software for it.

Download Latest Graphics Driver

If there isn’t any external graphics driver installed, then check for integrated graphics driver. If you’re unable to find out graphics driver for your Computer. Then you can use driver updater software. Personally, I suggest you use Uniblue DriverScanner.

Solution: 5 RESET Windows or Install Again.

If nothing works, then you can create a backup of important files using Safe Mode. And, then by using bootable Windows USB Drive, you can install Windows Again. If you have never installed Windows before, or you want to install the latest version of Windows 10. Then follow this article on install Windows 10 creators update.

That’s it. These are the only solutions which you can try to fix this error. Error occurs due to the corrupted or incompatible graphics driver. That’s why I have mentioned solution related to display drivers only. You can uninstall recently installed Windows or Graphics driver. Or, you can rename file name, that causing this error.
