Hello there,
You can try the memory test to find the driver causing this issue
The Memory Diagnostic Tool is used to verify and test the RAM. It is started for checking RAM for any faults while working on your system. It helps you to determine if any problem is occurring due to hardware failure including RAM, motherboard, and others. This process is done by running a set of tests.
ntkrnlmp.exe is an executable file associated with Windows Operating System. When Windows OS starts running in your computer, the programs that contain ntkrnlmp.exe will be executed and loaded into RAM and runs there as a NT Kernel & System process.
The graphics card driver corruption is one of the main causes for the ntkrnlmp.exe blue screen.
Hope this resolves your Query !!
