PC Short Electrical Sounds

[Loki Odin]

I keep hearing random Electric Sounds coming from my PC.
After someone's suggestion i sent my PSU for checking and it wasnt the cause of it.

Google results pointed at the CPU Fans (the sticker loosening and getting trapped between the fan and grill) and Motherboard (loose resistor/solders)The sound is too random and i it doesnt cause any distortion in the display.

Read somewhere it could be due to the GPU but the sound rarely occured when i ran Games on max details (Sometimes it didnt occur for the whole day or sometimes it would occur when im running Photoshop) yet im not sure what the cause is. I cant be sure if i should unplug my GPU and run the PC for a whole day since the sound is too random.

I'm using one of those Stabilizers commonly used for Freezers/Refrigerators and when turning the power on the stabilizer's plug sparks a bit (Non-continuous) but the sound seems to have somewhat a pattern; it emanates from the PC when im starting it for the first time (that day) but doesnt recur if i restart my pc and restard the stabilizer as well.

Any help will be appreciated.

is it like whirr and sometimes gets annoyong and sometimes totally disappears. I suspect PSU has something loose in it, when in case the vibrations cause the rattling.

More like a 'bzzt'
Had my PSU checked and it wasnt the cause.
Lately the sound duration and frequency increased so i removed the side panel to inspect (had to unplug the Chasis fans) and the sounds stopped soon after i started the PC. It's been a week since i last heard the sounds. 2 of the Fans were directly connected to the motherboard and the connectors showed no damage; not sure what caused the sound but im keeping them unplugged.

I had a similar problem once, in my case it was just loose and naked wires inside the pc (from the fan i think) touching the casing.
