    Lightly scratched i7 2600k and strange motherboard electrical noise

    AkumA

      Hi,

      I've just got back my motherboard that has been tested by the authorized support center.

      The problem is the following: after I've changed the mobo (it was a P67 with the bugged SATA) and I get a strange noise from the new one.

      You can hear it well around the processor area and seems to derive from the capacitors. Hearing from my chair seems like a louder hdd noise. Getting closer seems like an electrical charge that makes a "fried" noise. Same noise as making the oil boiling while you're cooking something in it. The problem is that that sounds come and go and I can hear them through my guitar amp and PC speakers!! It clearly generates a bothering magnetic field and seems like an electric charghe..

      I've a very very thin spot in the processor that has been scrached with an angle of the cpu cooler base. It's a tiny spot and it's not deep at all. Something like a little dot made with a thin sphere pen.

      The processor works and I can use everything as I used it before in performances and temperature.

      Since the support heavily tested the motherboard with no noises: is that little scratch the responsable? Have I reached something vital?
      Or could it be, like support said, something case/alimentation/graphic card related?

       

      Thanks in advance for help.
