Red bars on macbook pro screen and freezing?

Question

macbook

Hello!
Recently, such a problem has suddenly appeared: during operation, the laptop freezes sharply, the screen is filled with gray. After a hard reboot, red horizontal stripes on a gray background appear on the screen and the system does not boot. After several unsuccessful attempts, the laptop boots up and works stably until the next such freeze. When it freezes, it starts to get very hot and the
macbook pro 15 "early 2011 coolers accelerate. I tried to exclude a possible overheating, when it freezes, there
is no heating, the already frozen heats up.
