I have a HX 750, 1 year and a half now. Just recently about the least 2 months, ONLY when I play games. And ONLY if I'm in the loading screen/menu. My PSU will make a screeching noise that I suppose is coil whine. But it is so strange that it only happens in games, only in loading screens and menus. Like for example in Killing Floor, the load times for games are so quick, it'll make a brief screech sound and then go away when the map is loaded.
To add on to that, it's not every game, I only noticed it in all STALKER games, Killing Floor, I think in GTA 4, that's all I can name for now.
And to make it even more strange, today when I was messing around in STALKER Clear Sky's option menu, when I click a drop-down box, the screech noise changes pitch, and sounds deeper, but once I let go of the drop-down box it goes away.
I don't know if anyone had this before, but can anyone relate? Or give a reasoning behind all this?
