Hello to everyone! I am new to the forum and i apologize if i am posting to the wrong section.

I have a problem. Yesterday i bought a studio monitor speakers and a new USB soundcard. When i plugged them in i've noticed a strange noise like clicking and buzzing coming from them. It is still here ... It is annoing and i would like to get rid of it!
I've tried them (speakers and SoundCard) on my notebook and they worked just fine. Then i tried to reinstall/update the drivers of my soundcard, videocard,marvel/intel usbs and so on. I even reinstalled windows. What i notised then is that the noise is apearing only when the windows stars to load. It was not that likely then to be the earth ground of the power supply, but i changed it nevertheless. I checked cables, tried to run the PC with only 1 stick of RAM, HDD(pulled outside of the case) and 1 Videocard, detouching the front console of the case(i tought it might be some LED light cousing disturbances).
The strange thing is that some 2 weeks ago i have changed the PSU(Chieftec 950W / a good one) with a brand new Coolermaster Silent Pro 1000W. My PC was reseting and starting for a second then reset and so on(with my old PSU). Why i am telling you that is because before diyng completely my PSU was doing similar clicks and buzzes.That forsed me to check the new one and if i put my ear near to it it makes some buzzing too.. not that loud like the old one. I am wandering if my speakers are amplifying that sound or something..
I am wandering also from where comes the problem..

what i've not tried is to reassamble my PC on my desk to check if it's a case problem..

My PC specs are

MB: Asus p6x58d-e
CPU: i7 950
RAM: Corsair Dominator 24gb (2 sets x 3 sticks)
HDD: WD caviar black 1tb.
PSU: coolermaster silent pro
and my case is thermaltake element V full tower
and 2x g -forse 470 gt .
Win 7 64x

Thank you very mutch for your patience reading that.
your help will be really appreciated!

Best regards

Alexadner

Breadboarding would be a good test.

Does this happen from all USB ports?

Hi Proximon,
thank you for the quick response!

Yes it happens from all USB ports.

Something is probably grounded wrong or the PSU is generating EM noise. There are two or 3 different versions of Silent Pro 1000W. One is good, one is OK, but an old design and the other is unknown. CM is not a good company to buy PSUs from though.

Hi Proximon,
the exact model is CM SilentPro M 1000W - RS A00 AMBA J3 . I am sorry to hear that it is possibly not a good PSU. I am not a big specialis and it was a recomendation from a friend.
So in your eyes it is not that likely to be the MB.
I will try to breadbord it tonight after work.

I don't know the exact sequence of the processes and i am trying to understand why it happens only after windows starts to load. I mean is the soundcard taken in consideration after that moment and before that there is no signal/electricity coming to it?

It's the OK but old model. Could be fine, or could be the problem. You would have to swap it out to find out.

Really anything electrical could be the issue, but things like case fans are unlikely. Your computer doesn't use much power until the OS fires up, so it's not surprising you don't hear it during POST.
The more power involved the more likely the source of the noise. If you had just installed the board in the case I might suspect a bad contact somewhere.

I've seen this sort of thing clear up by simply re-seating the video card.

Thank you Proximon, i will try to reassamble it tonight. If it still not doing well i guess i'll wait for my older PSU to come from repair and then will try it out.
Anyway i will post the results.

Just a quick question. What do you think about the marvel SATA 3 ports on my MB.
I had some driver problems recently. Is it woth to use them with that HDD (6gb/s on paper) as it will not overreach the ~380 mb/s if i connect it to the "normal" sata2 port? I'm asking you because maybe i am missing something.

Thank you for the attention and your dedication!

No it's not. And I notice many Marvel port issues. Best to leave them alone when you can.

Ok, i think i found the problem. It seams to be my MB Asus P6X58D-E, i am not 100% sure but this week i will flip it to confirm. It seems to be a common problem with the X58 cards (not only Asus ones). I've noticed that when i lift the ground from my speaker's power cable the noise disappear. Though a ground lifter would be a temporary solution that do not solve the problem from its root. It is not a firewire problem, i flipped the PSUs,breadboarded, tried another set of RAM, new HDD, and to disable the CPU power management from BIOS (C1E ... ).

Thank you for the help. I will post the results ..
