Windows 10: Lan port makes cricket noise even before pc turn on.

I got my new prebuilt pc, and when I plug in the ethernet cable it's start making a cricket sounds, 1 sec between the noises and its constant. It only makes the sound if the power cable of the PC is plugged in too. After I used a bit the PC, it got quieter but after re-plugged it, it got the same. The noise not coming from exatly where the cable connects.

PSU making cricket noise, is it going to call it quits?

Occasionally I have a cricket / chirping noise from inside my pc. Haven't really determined whether it's the PSU or something else in my case.
So far everything's working fine though, and I first heard the noise months ago. It only makes the noise once when the pc is switched on.

 

PSU making cricket noise, is it going to call it quits?

Has anyone had a PSU make cricket noises every now and then?
My PSU never used to do this until I changed the motherboard from a ABIT AV8-3rd eye and Sapphire X1950pro 512mb AGP to what I have now.

My PSU a Enermax Noisetaker 600W has been making a cricket like noise on and off recently.
My PC has been running stable except for the vcore jumping from 1.45v to 1.49v all the time but has been dping this since I installed the motherboard.

If the cricket noise means the PSU is about to die, what PSU would be suitable for my rig?

I don't want to get a PSU which is excessive but just more than what i need.
I'm looking at Enermax or Silverstone at the moment.

I won't cheap out on PSUs as I've seen what happened to my mates PSU.
Big Chief PSU send smoke signal before death.
