Macbook hangs once an hour. Why?

Question

macbook

macbook pro mid 2012 hangs once an hour (regardless of the degree of workload). Changed the cable to ssd - did not help. Formatnul and installed a new system - did not help. the computer works without brakes, smoothly, but exactly once an hour it hangs tightly and does not sag itself. forcing the power button saves the day. Turns on, loads quickly and then runs smoothly for an hour. Need help! Why is that?
