Why do you see the “System Thread Exception Not Handled” Error? 

To begin with, System Thread remains 90% responsible for performing tasks on the computer system by allocating a unique thread code to each task. Whenever a user conducts a task on a PC, the entire virtual system sends a task request to the System thread. As a consequence, the system thread delivers code segments to the PC, and it further performs tasks on the user’s behalf. 

“Exception” stands for “a general rule not followed.” Thus, by definition, System Thread Exception Not Handled is a type of error under which a code segment remains unwilling to send commands to the computer. Here are the following reasons why it happens: 

#1: Drivers Failure or Malfunctioning

Now, it is crucial to note that System Thread doesn’t crash due to a single driver’s malfunctioning. For example, if the audio driver malfunctions solely, you may see a “No Audio Output Device is Installed” Error. However, when multiple drivers crash or begin to malfunction, it becomes a distressing case of “System Thread Exception Not Handled.”

The reason being, if more than one driver on your PC doesn’t work, it wouldn’t be able to transfer data correctly. Furthermore, performing tasks such as downloading files, accessing browsers, or playing music will be impossible. As a consequence, the PC will go into “Blue Screen of Death.” It will request a RESTART. 

#2: System Thread Exception Not Handled? Corrupted File System or Data

Presuming that you are using a PC for real-time entertainment purposes like downloading movies from proxy servers or playing high-range games can cause it to collect corrupted files off the internet. The scary part is that corrupted files multiply themselves easily. Before you know, a single corrupt file multiple into 100 new corrupted files. At last, the PC shuts down entirely or goes into the Blue Screen of Death more.

#3: Malware manipulates Graphics Driver

You may wonder why you are dealing with Blue Screen of Death in the first place? Here’s a simple and logical answer: Graphics driver corrupted. When you download or perform any activities on a computer using an unknown source, malware enters the system. At first, it may not harm the computer in a way that you can observe. However, at one point, the malware starts manipulating the Graphics driver, due to which the entire screen goes off. 

As a result, “System thread exception not handled” will appear on the screen. 

#4: The system thread is unwilling to catch the error

System Thread Exception is a classification of error where your PC is dealing with an unknown error. When the system thread couldn’t catch this error, it directly goes to Blue Screen of Death in order to protect hardware and software from permanent damage. 

In many cases, BSoD also comes with digital codes and unknown files’ names. They may be the corrupted files that caused the error in the first place.

#Method 3: Locate faulty files or driver and rename it

When a System thread exception not handled error appears on your screen, it means that the system thread is unable to detect a faulty file or driver that may cause damage to the PC. In many cases, when the PC goes to Blue Screen of Death, it mentions files names and drivers which are causing the problem. The prominent way to deal with it is by renaming the faulty file or driver, which System Thread will no longer detect as faulty. 

For example, a file with “.sys” in the end remains problematic. Yet again, it is only a temporary solution. 

Here’s how to pursue this method: 

  • First of all, access the command prompt. 
  • Use Windows key plus X key shortcut. 
  • Now, type the command “C:”
  • Press the enter button. 
  • Then type the command “dir” and enter. 

This command will automatically detect the targeted folder. 

  • Type the command “cd windows\system32\drivers” (use D: in place of windows if windows are not the targeted driver).
  • Press the enter button.
  • Next, type the command “ren driver name. sys driver name.old.”
  • Press the enter button.

Let’s suppose the faulty file name is wikjag.sys. Thus, in the place of the driver’s name, type “wikjag.sys” in the above-mentioned command. 

Finally, restart the system.
