the problem with the UE4

Hello everyone. I for some reason during the turn off laptop compilation. AMD 5750m , Radeon 6650m , 8 GB RAM , HDD 1TB , OS Windows 8.1 , С 95

You’re going to have to be more clear

compiles the model and then turns off by itself.

UE4 has no ability to turn of the machine, the best guess is that your CPU cooling system is faulty and the system is shutting down due to overheating.
