My new laptop is randomly freezing. This freezing occurs rarely - every dozen days. However once happened just after previous. The problem is that I cannot find what causes this freeze. I use this laptop for work so stability is very important.
What I have checked:
- system logs (/var/log/) - nothing found
- memory test - OK
- different desktop environment test - Cinnamon and KDE - both freeze
- different graphic drivers - nvidia-367 and nvidia-375 - both freeze
- added processor.max_cstate=1 intel_idle.max_cstate=0 in grub - it seemed to fix problem but after dosen days the freeze occured again (befor this modyfication freezing was occuring every few days or more often)
I have suspicion that problem is somehow related to using firefox, but still the program should not hang whole system.

What more should I check? Where is the problem? Is it related to Linux Mint distribution? Is it hardware problem?
The freezing occurs also on Windows 10 - during installation (if I leave laptop for a few minutes without touching mouse or keyboard) and after installation (without system updates). After freezing screen is malformed as on Linux.
I have updated bios to E5CN56WW version - still problem occurs.
After installation 4.9 Kernel there is no network on my Mint and other problems occur so I could not test this Kernel.
