Fixing the Kmode Exception Not Handled Error
The kmode exception not handled error is one of the most common blue screen errors for Windows users. If you’re experiencing this issue, there are a few things that you can do to fix it.
For starters, disabling fast startup might help solve this problem. This is a Windows feature that allows your system to boot up faster, but it can also cause driver problems.
Fix 1: Disable Fast Startup
If you are experiencing kmode exception not handled nvlddmkm.sys on your Windows system, one of the easiest ways to fix it is to disable fast startup. This feature is similar to the hybrid sleep modes of previous versions of Windows and saves some of your system’s state to a hibernation file.
However, this feature can also cause BSOD errors because it may not load drivers and kernel properly. That’s why it’s recommended that you disable it when you need it, such as if you have problems with updates or want to set up a dual-boot system.
To disable this feature, first open the Control Panel and navigate to Power Options. Click Choose what the power buttons do and then uncheck Turn on fast startup option. After that, restart your PC and check if the problem has been fixed.
Fix 2: Restart
When you see a blue screen error that includes kmode exception not handled nvlddmkm.sys, there are a few things you can do to fix the problem. One way is to restart the computer.
This can help to remove any temporary files that may have caused the BSOD. Another method is to run a system memory test.
If this doesn’t work, you can also try running a hard drive diagnostic program called CHKDSK. This will check your hard drive for errors and repair them if necessary.
The CHKDSK command can be entered from the Windows search bar or by clicking Run as administrator. It’s important to close the cmd window and restart your PC after running it.
The kmode exception not handled error is probably caused by an outdated driver, so you should update the driver to solve the issue. The easiest way to do this is by using the Device Manager.
Fix 3: Run Windows Memory Diagnostics
Running Windows Memory Diagnostics is a great way to check your PC’s RAM for any errors. It can also help you find out if your computer has any hardware problems like overclocked RAM or damaged RAM chips.
Often, memory errors can cause your computer to crash, freeze or display a blue screen of death. This can be annoying, but it’s usually a sign that the physical memory is defective and needs to be replaced.
The first thing you should do is restart your computer and then open the Windows Memory Diagnostics Tool. This process may take several minutes, so be prepared to wait.
After restarting, the Windows Memory Diagnostics Tool will start running a series of tests on your RAM. If it detects any issues, it will inform you with a status bar.
Once the test is finished, you will be able to see its results in the Event Viewer. Fortunately, the tool also offers advanced options so that you can customize it to your preferences. You can adjust the cache setting, set how many times to repeat the test mix, and disable any unnecessary tests.
Fix 4: Update Drivers
A common cause of this stop error is faulty device drivers. Generally, updating drivers or rolling them back to their earlier versions will solve this issue.
However, in rare cases, you may have to work your way through several more advanced fixes. In these situations, it’s critical that you identify the driver that is causing the bug check BSOD and fix it.
First, identify which device drivers are associated with the BSOD (usually by denoting their file name in the bug check). You can do this by running BlueScreenView, a free app from Nirsoft.
Then, update all of the drivers that are listed by name in the bug check. This will fix the BSOD for good. If you are using a third-party application that uses hardware acceleration, disable it to see if that fixes the problem. You can also try disabling fan control software that might be affecting your graphics card’s performance. For example, you might be getting this BSOD when using MSI Afterburner, which lets you monitor your hardware in real time.
