Preferred auto mode restarts the system | Ubuntu 440.59

By default, the powermizer setting “preffered mode” are set to auto mode. When the load increases, for example, in the game “Path of Exile”, the computer restarts! I was able to identify that switching to adaptive mode solves the problem!

My friend had the same problem on the windows system with gtx770!
