So, Let’s See How to Fix Kmode Exception Not Handled In Windows 11, 10, 8 & 7

So, you’ve recently decked out your computer with some snazzy new hardware upgrades, huh? Well, if you’ve been running into some pesky issues lately, especially right after those upgrades, I’ve got a nifty troubleshooting tip for you: try stripping it down. Yeah, I’m talking about taking off those fancy additions you’ve just slapped on and see if the problem magically disappears. If it does, give yourself a pat on the back because you’ve just unmasked the troublemaker.

Think of it like this: if removing the recent hardware fixes the problem, it’s like catching incompatible drivers having a spat at a Windows version party. They just couldn’t see eye to eye.

On the flip side, if you’re only getting the error when using a specific software application, maybe that program just needs a breather. Try giving it a clean reinstall or, if you’re feeling fancy, upgrade to the latest version. It’s like sending your software on a spa day, smoothing out any wrinkles in its relationship with your operating system.

Now, sometimes your operating system might run into a Kmode error while installing or running external USB device drivers, leading to that dreaded BSOD (Blue Screen of Death) appearance.

A simple troubleshooting step you can take is to unplug all those USB buddies from your desktop or laptop and start fresh. Strip it down to the basics, like your good ol’ mouse and keyboard. Let your computer breathe without all those unnecessary peripherals and see if the BSOD keeps haunting you.

And when I say “remove USB”, I mean unplug and disconnect all USB-connected devices like printer cables, scanner cables, webcam cables, external hard disk drive cables, etc., except for your trusty mouse and keyboard.

If the BSOD seems to fade away after ditching some USB devices, it suggests a potential driver issue with one or more of your connected hardware. In that case, start reconnecting one USB device at a time and keep an eye out for errors. If everything seems hunky-dory, move on to the next USB device and repeat until you pinpoint the troublemaker. Once you’ve got it, reinstall the drivers specific to that hardware component. Easy peasy, right?

Troubleshooting Drivers Related Issue

In about 80% of cases where this error shows up, it’s usually because of driver issues, which can be incredibly frustrating. But here’s the good news: you can often play detective and figure out which driver is causing the problem. Just look for the file name that comes with the error message—it’s usually shown right next to it and looks something like ‘xxx.sys’ or ‘xyz.sys’.

Alright, so here’s the deal: if you’re staring at the dreaded BSOD (Blue Screen of Death) and it’s not dropping any hints about which driver is causing the chaos, the usual steps we’ve talked about might not cut it. In those frustrating moments, it’s probably time to give this tutorial a rain check and go scout for a more thorough guide listed below that can tackle this mess head-on.
