Here is a simple and fruitful article that discusses the meaning of the “system_thread_exception_not_handled” Error, the time of its occurrence, the reason behind the happening followed by 5 possible methods of fixing it.
There are times when we run the power button of the computer to start it, but it does not start properly. Instead, there is a blue-colored screen that pops up along with a common error message that turns up within 10-15 seconds after the blue screen appears. The blue screen is called the ‘blue screen of death’ and the message that pops up is “system_thread_exception_not_handled”. The same thing can happen when any system is being booted.
What does the “system_thread_exception_not_handled” mean?
The message in the error box is directly associated with an indication that a certain system thread in the system has generated an exception; an exception of an error that the system handler had not caught. Just the reason why the handler failed to catch the bug and fix it, the blue screen of death appears on the screen. Within that time, the device is trying to collect the information regarding the error. As a result, the error code comes up.
There can be two kinds of messages on the code: a letter series as a file name (if one is lucky enough) or a number series. The code sometimes carries some number series like 0*0000007E or 0*1000007E. If the code contains a letter series, which is supposed to be a file name, it can show like this-cpvorejejvf. sys, cdfnvfingbnow. sys, or many others. To resolve this issue, one needs to reboot the whole system, requiring using safe mode to break the chain.
When and why this happens?
There are two times this error can occur in the system. First, if the system is restarted. Second, if the system is booted from the shutdown. Thirdly, this error can occur sporadically as well when the user is using a program that needs specific graphic drivers for work.
Also, this error happens when the system is not compatible with the driver that is installed, specifically the graphic drivers. The driver can be outdated, misplaced, or simply can be corrupted.
