mechanical "buzzing"

[JAW96]

so I have been getting this buzzing recently, and have been unable to pin point it, and was wondering if any of you have a idea what is causing this noise

 

a quick over view of my PCs past issues

 

-if it got cold (as in below 50) the top fan would make a low toned grinding noise do to a bad bearing (still need to get around to oiling it)

 

-would crash while watching YouTube videos (solved had to turn off hardware accelerations, because flash sucks)

 

I have done some research, and people keep saying it is bad caps, but I personally don't think that is it, because as said before it has a mechanical sound to it not the sound that dying caps make (I have experience with that noise, lost 3 dish receivers to that). 

 

one more not it mostly occur late at night, and early in the morning, have yet to have it occur during any other time of the day.

It's probably coil whine, i have the same with mu psu when i'm gaming because i put a lot of stress on it, getting more and more common sadly... And there's nothing you can do, unless you are prepared to change the caps which i don't recommend unless you know what you're doing. It's just because the caps are a bad quality and not because they are dying, brand new caps can have this problem to so...

linus made a video about it: 

Also possible explanation  for the coil whine occuring during specific times of the day is probably the "clean-ness" of the power you are receiving and how your psu handles it.

A new psu can solve it, but that's never guaranteed!

Maybe it's the PSU buzzing, it's common and doesn't mean it will die.

thanks, but mine sounds considerably different

Could you maybe record it? Would help a lot

Also coil whine can sound very different from that, my psu for example makes a lot lower pitched noise. I must admit that the coil whine in the video is really high pitched.

I would, but my pc is quiet right now, it is a continuous upper-mid pitch to it
