Mother ASRock B365M-HDV problem!

Hello, in General I collected the PC, everything is OK, run all the first time (without dances with a tambourine in terms of flashing BIOS), BUT here's the problem, after the installation of Windows in the housing of the computer, a strange noises at light loads (when opening the browser when scrolling vidyuhi in YouTube, it happens even when Windows is loaded) is reminiscent of the chirping! Googled this issue, 80% of all write either video card or power supply (video card RTX 2060 , the power supply unit PowerMan 600W on). Went through process of elimination, vidyahu gave it to a friend for her day of errands in toys various furmark and stress testing chirping no! The power supply was tested on an old computer chirping - no!
Remains motherboard! If you listen then the chirping coming from the motherboard chokes, but they're closed type. As they would be if the chirping this is not a warranty case. But the sound of irritable. Even work uncomfortable. The system unit stands next under the table. Can someone faced with this? Still suggest to change the power supply, supposedly the load is different and the blocks of these China-China.
