high pitch buzzing sound from tower speaker

[Sharif]

After i removed the RCA cable from both the satellite receiver and my pc,the sound was gone 

also when i move the cursor it also effect the sound but my Z506 is connected  as well and it isn't making any sounds 

 

but what is causing it?

Either bad connection, faulty onboard, but it sounds like interference from the mouse.

Try using a different mouse maybe.

I recently changed my PSU,can that be the cause? 

and even after disconnecting audio cable from computer the sound persists and oddly its gone now......... after a match of loadout

@everyone  (it would be funny if that was somebody's name  ) 

 

Ok i think this might be the reason  

so today after millions of seconds i put my computer in max power saving mode and the noise was gone with i put it in high performance mode it came back again 

they are all connected to the same extension cord 

where  is the disturbance happening?

could just be standard coil whine, have you checked the power stip? Those are known to have a humming noise (mine do, but they're soft enough to not be an issue)

the power stip specifically, not really the extension cord.

But its new..........

the sound comes from only the speaker that is connected to the same extension cord while my z506 doesn't it is connected to a different extension cords

Ok i have two extension cord in one place both are coming from 2 different places but after that was fixed the right speaker stopped working (not loose connection) this happened before but it normally fixes itself  :blink:

even after connecting it back it still doesn't (well it works but in a very very very low volume)but annoying noise came back and then i plugged it back again to another place,just waiting for the magic to happen 

thanks anyway

If only i lived in US or canada or even UK..............................

thanks anyway 

i fixed that problem but i did some googling and i might have a bad capacitor because one of the tower speaker is working but in a very low volume

like when i touch it i can feel the beats but the volume is low you can't hear it  

 

i fixed it last time by  increasing the volume by a lot and decreasing it again but this time it doesn't feel like working 

also it happened a other time but that time it fixed itself
