Two days ago I made a PC myself. I made it for mostly editing and slightly gaming. The next day I launched GTA 5 after 5 mins the pc got deadlocked, nothing works totally frozen. I shut down the pc and changed the thermal paste of the CPU. While I was changing the thermal paste the Ram was hot. Then the next time I watched the CPU temps with HW Monitor and the max was 60 and the value was between 40 to 50. All settings were set to very high automatically and still got 60 to 62 fps when benchmarked. Even after the Temps were low it still got deadlocked. I contacted the people whom I bought the parts from. The guy who gave me the CPU, Motherboard said he never overclocked it and he bought it from someone else. He also said he never experienced something like this before. Then I asked the guy who gave me the GPU he said it was slightly overclocked but haven't had any issues. I haven't tested any other games. It deadlocks only when playing GTA 5 for now, and the CPU cooler seems to make it cool always. This is my computer parts: https://pcpartpicker.com/list/gt43mq . I bought everything new except the mobo, CPU, CPU cooler and the GPU.
