I made an Live Mx Linux ISO pen. I have tested my mem. No errors.
After this I run Mx live distro and test it with the same way. Its frozing. I think you are right. Huston we have a problem. 
I have installed word, acrobat, I watched film on Win - withou any problem. Copified 100gb⌠without any problem.
My only idea is the BIOS (which is the newes) but secure boot is off and there is no other important thing which Linux kernel crashed this way.
My problem is solved as far as I know now. Stay on my old asus x550vx. I dont want Win (which is work perfectly on Hp), but on my old Asus Mabox boots and runs much faster. I can do my job on Linux with wps and quoppa.
Finally, thank you for your kind help.
Best regards
