For any Windows user, getting the BSOD (Blue Screen Of Death) screen is a complicated experience. Furthermore, if the stop code or error code on the BSOD is kmode_exception_not_handled, the situation becomes more challenging. Read through the article to learn the best ways for a stable fix.

What Does Stop Code Kmode_exception_not_handled Mean?

The kmode_exception_not_handled stop code is one of the many BSOD problems of Windows systems. It indicates that a kernel-mode program raised an exception that the error handler didn’t catch.

On a Windows PC, you mostly see this error if you just add new internal or external hardware to the system. For example, an NVMe SSD chip, a graphics card, or a network card. If the hardware isn’t compatible with the installed Windows operating system’s built-in driver library, the error is highly likely to occur. Thus, it’s often suggested that you install the hardware driver first and then connect the hardware to your Windows PC.

Sometimes, faulty system service applications or device drivers can also trigger this BSOD error on your PC. Not to mention, other occasional but definite causes of kernel mode exception issues are Interrupt ReQuest (IRQ), BIOS incompatibilities, and memory (RAM) conflicts.
