Thanks for your reply.
The system is working fine, but sometimes when we process large 3D files and light renders, the system need to work hard and the OS (windows 10 - 64bit) can freeze for a bit. Maybe the problem is at software level and not the hardware?
Maybe I can consider to overclock it?
This is my complete system configuration:
Intel Core I7-5930K
