Faced a new problem, despite the fact that the system was recently installed on a blank formatted hard disk. Games (GTA 5, The Crew, Need for sped 2016) are suitable for the maximum requirements and used to be played on high graphics settings at 50+ FPS. Now, no settings have changed, nothing has been installed and the game began to brake wildly periodically. I play a couple of minutes normally, then it starts to slow down, 20 seconds is normal, it slows down again, it happens right up to the hang of the game, which only helps reboot the PC. I ask to help or assist with the given problem. It's impossible to play.
