So whenever I start Crysis, or attempt to change the settings in certain games, my newly built PC will crash and restart, with a Kernal-Power critical error in the Event Viewer. In other games, I will hear a high-pitched whining noise I have pinpointed from the PSU. It will change pitch and frequency depending on what I'm doing in the game. I'm fairly certain that the PSU shouldn't be making any such noise, and therefore the crashes are a result of a faulty PSU. However, I'd like to be sure that case isn't that the PSU is fine and there's another faulty component which is drawing power improperly causing the issue (i.e. the GPU, as this only happens in games). Thoughts? Should I RMA the PSU or is it possibly something else?
