So, I builded a new PC about 5 months ago. It has worked perfectly, but my PC caused random freezes back then. Didn't really mind, because it happened couple times and stopped. Now, it has started again. Im getting random freezes during games and sometimes PC just restarts itself midmatch. No idea what can cause this?
