I have fixed my 2 computers on the wall without casing on a wooden sheet …
every thing is working as planned but there is this constant humming noise on 1 of the computers(even if mic is removed)…
The sound changes with mouse movements, i can hear clicks of hard drive and funny sounds when i minimize or maximize windows…
I can hear the sound then i unmute the input monitor..
I think it is some grounding problem but i can not fix it even after grounding the system ….
Another thing that makes things more confusing for me is that… both the computers are fixed and wired in the same way… One has humming problem and other is perfect….
I Swapped power supplies ..No luck …
I attached wires with MB and HDD then grounded it with powersupply but no luck…
The only thing that stops it is when i half insert the mic pin …. then obviously my mic dont work ….
Can any 1 suggest me What shall i do ?
If u guys need more info….Feel free to ask…
