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?
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.
Solution 01: Reboot The PC
When you’re on the kmode_exception_not_handled error screen, you can’t access the usual PC power on-off interface. Here’s how you restart the system:
- Press the reset button on your desktop or laptop PC to restart.
- If you don’t have a dedicated reset button, long press the power on button on the PC.
- Keep pressing until the display screen goes black.
- Now, let go of the button and press once again to restart.
Solution 02: Remove the New Hardware
If you see the kmode exception handling BSOD error after installing new hardware to the PC, do the following:
- Long press the power on button to shut down the PC.
- Disconnect all connecting cables to the PC including the power cord.
- Open the PC chassis cover.
- Touch a grounded metal surface to discharge static electricity or use an anti-static wristband.
- Remove the hardware you just installed.
- Close the chassis cover and connect all the cables.
- Power on the PC.
Solution 03: Clear CMOS or Reset BIOS Chip
This method will reset the CMOS or BIOS so that it can use its default settings when you power on the PC later.
- Turn off your PC and unplug it from the power source.
- Open your computer case to access the motherboard.
- Locate the CMOS battery, a coin-cell battery.
- It should be near the memory slots or on the left side at the bottom half of the motherboard.
- Remove the battery.
- Wait for 20 seconds.
- Re-install the battery.
- Close the PC case and connect the power cord.
- Power it on and the issue should go away.
You’ll need to update the device time after following this method.
