When it gets this error, usually Windows will try to restart itself. But, most of the time you’re stuck with an unresponsive computer. The only way out is to force shutdown your Windows and turn it back on. Doing this many times can even corrupt your files. What’s more, if you were working on something on your PC you would lose your work.As we’ll see, this is a Windows-only issue. We do not get this error message in Linux and macOS systems since they’re built differently.

What Causes the “System Thread Exception Not Handled” Error Message in Windows?

This error message is always associated with a system file or a sys file for short. To understand what causes this error message, we need to understand what sys files are. Sys files are stored in system folders such as C:\Windows, C:\System 32, etc.Sys files are used and updated by Windows and are critical to the operation of the system. Sys files mostly store device drivers needed for Windows. These files are hidden by default and do not show up under search results.Device drivers are programs that enable Windows to interact with hardware. Since they are just programs, it is natural for them to crash or stop working sometimes due to a bug or a hardware fault. If this happens, it crashes the entire operating system and thus you end up with the blue screen of death.

Prerequisites

Identifying the Sys File

Once you get the blue screen, take note of the displayed sys filename as shown in the screenshot below. Once you do that, use the following list to identify which device driver it belongs to.

Booting Up With Safe Mode

The Safe Mode is a convenient tool for fixing blue screen issues with your Windows. In this mode the PC boots with the bare minimum configurations. It disables all startup programs and device drivers. Through safe mode, we can fix any issues that prevent our Windows from operating.There are three types of safe modes provided by Microsoft.

Safe ModeStarts with minimal drivers that are possible to start the operating system. Even the internet connection doesn’t work in this mode.Safe Mode with NetworkingStarts with the same set of drivers and services as above. Includes networking services too. It is possible to use an internet connection for troubleshooting in this mode.Safe Mode with Command PromptStarts the operating system in command prompt only. Unlike the other two modes, this mode disables the graphical interface. It is possible to use the PC through Command Prompt commands only. This is useful when the system has trouble displaying graphical components.

Steps to Boot Into Safe Mode

To solve our blue screen error message, we will boot into the second mode,i.e. Safe Mode with Networking.
