Has anyone got any idea?
There are several possible causes. We could give you more help if we had the actual DMP file created. If it isnt a BSOD you can still create a DMP file.
Kernel power failure can be caused by an old BIOS so I would update that.
It can also be caused by a damaged system file so I would run a system file check by typing cmd in search>right click and run as admin>sfc /scannow.
I would stop overclocking for anything else you do may or may not work until you do
