Error: UNEXPECTED_KERNEL_MODE_TRAP BSOD on PC

Hi Madalin,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues with Blue Screen of Death on your PC. For further clarity on the issue, please respond to the questions below:

1. Are you aware of any changes made to the PC prior to which you weren’t facing this issue?
   
2. When do you receive the BSOD?
   

Based on the dump files you have shared, the file ntkrnlmp.exe is causing the Blue Screen of Death. The bug check UNEXPECTED_KERNEL_MODE_TRAP indicates that the Intel CPU generated a trap and the kernel failed to catch this trap. For more information
refer the article
Bug Check 0x7F: UNEXPECTED_KERNEL_MODE_TRAP



Usually, this error occurs if there is a hardware failure. If you recently added hardware to the computer, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. Run hardware diagnostics that
the system manufacturer supplies to determine which hardware component failed.



In addition, you can try running Windows Memory Diagnostic to check RAM corruption issues. Kindly follow the steps mentioned below:

1. Boot the PC into
   Safe Mode
   
2. Press Windows + S keys together to open
   Search.
   
3. Now type Memory and click on
   Windows Memory Diagnostic.
   
4. Click on Restart now and check for problems.
   
5. Follow the on screen instructions
   

Let us know how it goes.
