Static noise

[Rovillalob]

While playing games I get a static sound that adds to the normal game sounds, its not always there but once it starts all I can do to stop it is to close the game and open it again. I experienced it while playing Path of Exile and Deus Ex Mankind Divided and its not just sound, I get some unstable frame times and sometimes frame drops (both measured with the in-game measures from PoE).I also get some random pc shutdowns. I noticed that just before it happens everything freezes for a short period (1 or 2 seconds). This is the link,

The static noise could be coil whine making its way into your audio, it's a pretty common issue. Are you able to open a FPS counter and see if the sound changes as the framerate changes? It isn't certain to be this but it's a possible cause.

 

Your PC shutting down could be a billion things, overheating or PSU problems might be a cause though.

Is coil whine permanent once it starts? Sometimes it starts when the frames drop but once they get stable it continuous
