Similar sound for #MeToo
But, is it coming right after power on beep sound.

In my case it's, power on beep sound + continuous beep sound..

Are you sure..? because I don't think earthing will be disturbed automatically unless you change / rewire hardware.

That sound is not coming from buzzer/CMOS speaker?

Buzzer(CMOS speaker) sound is okay, It gives a single Beep with POST success.
The sound used to start whenever I powered on the machine,i.e.,cold boot start.
Continuous beep sound means motherboard has gone kaput. By the grace of God not in my case.

Earthing is fully okay, because on June 2020, I had to re-install the electric main wall board(PC connection board) with new wires,new indicator,new switches and plug sockets. All done by an Electrician from URBAN Company.
The guy knows his job well. After proper installation,he tested each plug socket holes with a multimeter and tester. He also checked the line coming from mains. HE HAD ALSO CHANGED AN AGED FUSE BOX IN LIEU OF MCB BOX (Havell's).
Pocket pinch was Rs. 1700.00 approx,with materials.

But the recorded sound you uploaded is exactly similar to continuous beep sound by buzzer.
Maybe sound recording problem.

Again I reiterate ,the Buzzer sound is very low. It gives a SINGLE BEEP onto my system.
The buzzer speaker is generally a wire attached with the cabinet.
But some cabinets don't have them.
I am using a

buzzer speaker.
It is functioning properly.
