hindi ok yun. wag ka na gumamit ng AVR

Cheap power transformers can 'buzz' as the laminations may be loose. Better ones are varnished so that it is all held solid. Cheap units may also be run close to magnetic saturation making them buzz too.
They can also make nearby steel panels / brackets vibrate if there is a strong radiated magnetic field.
It is mostly a 'mechanical' problem so lifting it out of the box will tell you if it is the transformer or it's housing that has an issue. DON'T fit insulation so that it may overheat but try rubber pads or whatever, maybe even noise insulating standoff 'bushes'.

palitan mo na lang yan ng power strip (extension chord) na may surge protector

kahit na branded pa yan the same issue happened. nag-loosen ang lamination ng magnetic wire layers nya
my recommendation remains the same.

baka UPS
UPS ang best kasi it also functions as an emergency power source kung sakaling may brown-out. problema lang pag nag-end-of-life na yung battery atsaka mahal.
ang AVR naman kasi nireregulate nya lang yung power surges para di pumutok yung power supply ng PC mo along with the other components. sya lang ang puputok (fuse) just in case may failure. but it just complicates stuff and a little bulky. it's just a glorified extension chord in my opinion
yung power strip na may surge protector naman, very practical. it basically does the same function as an AVR and is also very compact in size. keeps your PC safe from power spikes
