My new computer suddenly makes a faster piercing noise like its the fan even though I dont think its overheating, when I load bf4 and then it turns off thats it. Then I try and turn it on and it wont turn on when I click the power button I have to wait like 5 minutes. The computer doesnt overheat I'm watching the temps 55C when playing. Could it be my power supply? I have had heat issues for a while with my 4770k but its good now. Also I can play league of legends without this happening or any non FPS game. ex: League, Minecraft etc.
I don't think League is as CPU intensive as BF4, it kinda sounds like you may be having a major heat spike on the CPU but it would most likely throttle before it just shut down completely like that.
Why would it be doing this I already have exchanged once for another 4770k bc the other one was though to be defective. I have a noctua CPU fan and 2 case fans on being a cougar fan
