I'm assuming you mean there is an electrical hum through your amp/speakers when connecting the PC for playback.

 

How are the PC and HiFi connected? Optical or Coax or USB to a DAC? or an analog connection to internal sound card?

 

Is the PC connected to the same power socket as the rest of the HiFi?

While I agree "Everything may matter" working out what actually affects the sound is a trickier thing.

And I agree "Trust your ears" but equally don't allow them to fool you - trust them with a bit of skepticism.

keep your mind open... But mind your brain doesn't fall out.

thats right had it for a while used to be miner now its grown. yes phono connections to a motherboard. the hifi has a very expensive power condioner and cable system while the pc goes intoa surge block on a seperate socket. i also put on there russ andrews silencer to try to help.

 

any thoughts anyone as with a blacksilence for the mo the pc would sound rather nice

Can you plug the PC into the HiFi's power conditioner? Try that and see if it cures the problem.

i tested the cable seperate from the pc.

i used the dedicated mains i have for the unit which made a slight difference only, nothing at all much.

i do not know if it is a power supply issue for the pc or a motherboard issue?
