What is the Kmode Unhandled Exception and how do I fix it?

kmode exception not handled

What is the Kmode Unhandled Exception Although much rarer these days, the blue screen error page that appears in Windows when something goes wrong has long been part of the PC experience. It’s not always severe and often fixed with a simple restart, but anytime if you run into an error, that comes itself repeatedly. “Kmode exception not handled” is one such problem.

Fortunately, however, this is not a serious matter and can be fixed in a matter of minutes if you take the proper steps. Follow below to find out how.

Note: If you are running Windows 10 or earlier, if the blue screen does not allow you to start Windows, try the fixes listed below instead of a boot into Safe Mode and make changes.

What is Kmode Exception, and why is it not addressed?

The technical details of the Kmode Exception error are thorough and more than a little dry. In short, when applications replace each other’s memory, causing errors or crashing software, in the case of a blue screen, the entire system crashes.

Some software is corrupted, and the Windows error handler isn’t entirely sure what’s gone wrong. It just knows someone is, and it has caused the system to fail.

The likely culprit is the problematic driver.

Remedy: Disable Quick Start

The Windows 10 Quick Launch feature can be a catalyst for this problem. It’s a feature of Windows that allows you to recover from hibernation and shut down quickly, but it can mean that it reloads in possible driver problems.

Often, disabling QuickStart can lengthen your system or even fix the problem completely.

To disable Quick Launch, follow these steps:

Find “Control Panel” in the Windows control bar and select the corresponding result.

 Press “System and Security” and then “Power Options.”

Select “Select Power Buttons” from the menu on the left.

When prompted, click the blue “Change current settings” link at the top of the page.

Under Shutdown Options, clear the Enable Quick Start check box.

When you’re done, click Save Changes.

If you still receive the Kmode Exception error after removing it, or if you want to solve the problem without losing its benefits, you can try to resolve the issue at its source.

Updating problem driver

Because Kmode Exception Not Handled error is probably due to a driver problem, updating your driver can often be repaired. To do this, however, you need to know which driver is causing you problems.

It depends a lot on your system, but luckily, Windows usually gives you a good indication of the culprit. When the blue screen appears, you will usually see “Error: Kmode_Exception_Not_Handled”, followed by the name in parentheses. This name is the driver that is causing the problem, and we want to update.

Please perform a search for the driver to find out which hardware it is associated with, and then follow the instructions below.

Search in the Windows search bar, type “Device Manager,” and click on the corresponding entry.

Find the hardware that corresponds to the driver problem and right-click it—select Update Driver from the drop-down menu.

When prompted, select “Automatically check for updated driver software” and wait for the process to complete.

If this doesn’t help, you can always check the motherboard manufacturer’s website for a new driver version or Google hardware if the driver is included with the option card or other hardware. If so, download it and perform the driver upgrade manually by selecting “Browse my computer’s driver software” instead of the third step.

The process may take some time, but when you’re done, you should have a system that no longer throws Kmode Exception blue screen errors.

It can be your RAM error

If the problem persists after the above fixes, you will either have a bit of bad luck, or you may have a hardware problem that will cause your driver to become corrupted. If it turns to be the latter, the mostly culprit is your RAM problem. In this case, use Windows’ own memory diagnostic tool.

Find “Memory Diagnostics” in the Windows memory bar and select the corresponding result.
When you’re done, click “Reboot now and check for error.” Or alternatively, “Check for error the next time I turn on my computer” to save an existing job.

Wait for the scan completion during the restart. If serious errors occur, you probably have a faulty RAM that can very well cause the blue screen you replaced. First, try removing and installing RAM to make sure the connection is not loose. If that fails, the best bet at that point is to replace the hard stick or buy a whole new set.
