Hi!
I have just installed media center edition 2005 on my old computer, and connected some speakers, and the thing is, i hear some sort of interfierence coming through the speakers, infact when i am loading a program the interfierence gets louder, i have tried another set of speakers, and they are experiencing the same interfierence, any ideas what could be causing this?
Sound is onboard 6channel C-Media.
Hey Willz
This is not going to help as I am not actualy answering the issue…
I had a simillar problem with my ASRock onboard C-Media chip.
Then my mobo fried and my replacement mobo had the same chip but the problem was gone :eek:
Where are the speakers plugged in? Back or front?
If it is in the front - try the back and completely disable front audio.
This could also be some earthing problem.
The reason I mention earthing is that for example laptops sometimes emmit a noise through the audio outlet when you charge them, if the charger is not earthed…
ah, i am using 2ch speakers on my old comp, the motherboard is faulty as it keeps shutting down for no reason.
Sometimes a loose connection can also be a reason for noise.
I have checked for loose connection, there aint one 
well according to what sabashauli said it just the motherboard might be bad as well i had a 2 similar problems one was interference and the other was similar, anyways for the one i got a audio card, i did some searching and found thats what others did as well, for the other one i re-installed windows, i think a driver or AC 97 driver was bad or missing, and it was fixed. So it could be a couple things, windows has a messed up driver, the driver for the onboard sound might need to be updated, or the port might just be bad.
hmm, i might try re-installing the audio drivers, maybe get the latest ones, which i have never used becouse i think they are pretty crap.
