Buzzing noise from PSU print

[StaticSounds]

I got this buzzing noise coming from the print of my powersupply, while under load, see the video:Video around 0:40 for noise

I'm curious as to what might be causing it. I presume it's a coil or capacitor, any ideas?
I guess it's about time I buy myself a new psu.

Using a screwdriver as a stethoscope I located the noise to the transformer, I've read online that the adhesive between the layers of the laminated core will crack over time and the noise will increase so much for MTBF, I'm only at 20% of the expected life time and yet past the guarantee.

You... Touched the active components, especially near the AC Primary of the transformer, with a screwdriver while it was on?

Man up Arcygenical, it's only low voltage as they say
Jokes aside, it was with a VDE insulated screwdriver, and I wouldn't put it where it could shortcircuit my pc.

The noisemaking part, i assume is a primary transformer, which is marked: VRL39W004 0828 W-E-B-A
I can't find a datasheet on it or any usefull links on google, so I suppose there's no replacing it.
