 There are significant hazards to be aware of when overclocking a computer.At a mundane level some components will not work under too high a demand, and the computer will not work until the overclocked demands are reduced or mitigated.More seriously, some components are capable of being damaged or destroyed by increased heat or voltages routinely caused by overclocking if the user is reckless or uninformed, and therefore caution and some level of prior understanding is needed.
