Weird buzzing sound coming from my psu. I made a video and some pictures here:

Out of nowhere my pc started to make this loud buzzing sound to the point i could feel it resonating. When i checked it came from the psu or maybe the vent inside the psu.

When i turn on the pc when it had been off for a while i dont hear it, but the longer i have it running the more sound it make. Seems like a temperatur thing. I also noticed weird black stuff on a yellow thing on the psu, look to the picture for it.
So what do i do not? Is it broken?
