Error: DarkSouls app not responding

Hello. The problem is this: when you try to enter DS3, the Task in the dispatcher is either simply removed, or the white floor of the screen pops up and the inscription ,,DarkSoulsIII application is not responding. But this is only half the problem, if you go into heavy games or programs for an hour, then it will still start with a probability of 25%, but after an indefinite time it just causes the system to crash and auto reboot. Help me please!!!
