Hi,
I noticed that you are experiencing an error with a blue screen that displays the error message: KMODE_EXCEPTION_NOT_HANDLED.
To assist you with an effective and assertive procedure, I would like to check the following questions:
What is the make and model of your device?
What is the message or error code that appears next to the message: KMODE_EXCEPTION_NOT_HANDLED.
At what time does the message occur? Example: when using the Internet, when playing a video or game or even at startup.
Anyway, for a possible solution, I suggest that you perform the steps below:
Step 1: Safe Mode.
Start the computer by holding down the shift key and repeatedly pressing the F10 key.
As soon as it boots in safe mode perform a simple system boot, as some program at startup may be causing this conflict.
If in safe mode it shows the same behavior, skip to step 2.
Simple Boot
Press the Windows key + R type MSconfig and click ok.
In the System Configuration window click on the services tab.
At the bottom of the screen leave the option to hide all Microsoft services and click disable everything.
Click on the programs startup tab and click on open task manager.
In the task manager on the startup tab, disable all non-Microsoft programs, close the task manager, click ok in the system configuration and restart.
Note: after simple boot you will need to repeat the above procedure without safe boot and enable one program at a time to find out which program is causing this conflict and uninstall.
In case the above procedure did not work I advise you to go to the computer manufacturer's website and update all the drivers.
Step 2: Clean Boot.
In some cases, the external device or some CD / DVD can cause the system to boot which can cause this behavior, so I advise you to start the computer without any external device such as a USB stick, external hard drive, keyboard, mouse and CD /DVD.
Test and see if the behavior is repeated.
Step 3: Boot repair with media.
Perform boot repair using installation media or a recovery drive.
If you do not have a media, follow the procedure to create a repair USB drive.
To create a USB recovery drive.
Download Windows 10 on another computer, stick a USB stick on the computer, open the command prompt as an administrator and perform the procedures below:
Diskpart
List disk
Select disk 1
Clean
Create partition primary
List partition
Active
Format fs = NTFS quick
Assign
Copy the Windows 10 image files to the bootable USB stick.
Insert the Windows installation disc. Restart the computer and watch the screen to boot from the CD. When prompted, press any key.
After clicking on any key, as requested in the previous step, the Windows Installation screen should arrive. Click "Repair Computer".
You will be taken to the "System Recovery Options" screen. Just select the language and click "next". Proceed from Step 3, requesting the startup fix.
The computer will show a screen with the recovered system errors. After that, just restart.
This is a very useful and indicated procedure when you face problems with Windows startup, however, even if these behaviors are still showing after these steps, it will probably be necessary to format the HD and do a clean installation of Windows, but it is worth trying it before.
If the answer helped in any way, please mark it as an answer, if your question has not been solved, please post again.
I hope I helped, even more!
