KMODE_EXCEPTION_NOT_HANDLED

Possible solutions

Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.

1. Safe Mode and Drivers

   If Safe Mode is stable, check for recently added drivers or services.

   Steps to follow

   1. In the available login window, hold Shift and click Power > Restart; if it doesn't boot, open the Windows recovery USB option to Repair your computer.
   2. Get a recovery key for the encrypted drive and a copy of the files. Select Troubleshoot > Advanced options > Startup settings > Restart.
   3. Select 4 or F4 safe mode if provided. You may need your account password instead of a PIN to sign in.
   4. Compare performance; if stable, check for a recently updated driver. Usually, rebooting will return you to normal mode.

2. A more extensive system check

   If the error occurs even in safe mode, check your RAM, storage and system files.

   Steps to follow

   1. First, copy important files to another media if the system is stable. If the drive disappears or crashes, stop the self-tests.
   2. To check RAM, save your work, Windows+R type mdsched.exe and select reboot and check.
   3. Let the test finish and note if it finds any errors. One short successful test does not rule out all instability.
   4. For disk information, right-click Start > Device Manager > Disk Devices and write down the model; in its manufacturer's tool, check the health status without applying a wipe or a long test.
   5. If errors are found or the failure occurs again, report the results to the technician. Do not disassemble the RAM, sockets or power supply yourself.
