So let’s get started.

Why does the issue of system_thread_exception_not_handled happen?

One of the main common reasons is BIOS incompatibilities. The System_Thread_Exception_Not_Handled issue can also be caused by the driver like nvlddmkm.sys, Netwtw04.sys, and iaisp64 sys. Sometimes when you boot the computer, the screen flickers and turns blue. The system then enters into a loop of reboots where it keeps on rebooting over and over again.

When the system_thread_exception_not_handled error happens in Windows 10, it is mostly the graphic drivers that are to be blamed. They are either the old ones, get corrupted or incompatible for some reason. Thus several parts of them become unrecognizable by the Windows. Due to this confusion where it recognizes some parts and not the others, the error is caused. However, if you think it’s a big problem, it’s not true as it can be resolved by the simple methods we will be telling you.

How can the issue of system_thread_exception_not_handled be solved?

Since the reason for the problem is many, we will be dealing with them one by one. The major reason, as we all discussed, is the malfunctioning of the drivers.
Before starting the process, you need to check if there is enough disk space on your computer. If space is not enough, then use any tool to delete the junk files, which would clear up some space on the disk. The disk cleanup tool can be one of such help that you can use.

Sometimes, the message that appeared on the blue screen also contains the name of the file that caused the error. It can be something like system_thread_exception_not_handled (nvlddmkm.sys). The name written in the bracket is the name of that mischievous file, which means that it is the graphic driver called NVIDIA. In this case, where the error displays to you the file’s name, you begin the troubleshooting right, thereby targeting the particular file only.

The main idea is that once you see the file’s name in the bug check message, you start with finding out the nature of the file. You need to find out the location of the file on the computer. Then make a check of its properties or search about the file on the web if the system doesn’t revert any information about it.

As we know the reason now, it is obvious that you need to start treating the driver file. You may try disabling the driver or checking with the manufacturer for updates for the driver according to the situation. You can search for yourself if there are any updates available for the driver. If you find out that any new service was added in the form of the file, then you may try disabling it with the help of services.msc and see if that works out for you.
