-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Thank you all for the suggestions. I will apply some of them, as for moving the card, it already is in the farthest PCI slot available. I will, however remove the analog cables, as they pass rather close to the graphics card, and they might be acting as "antennas" to pick up the EM emitted by it (not to mention the rather big HSF the GeForces nowadays include :)). I guess a quick and dirty test could be to only mute the CD-In and Aux controls and see if those stop these sounds... Will report back. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFEyQ4dXM+XOp70dwoRAqsDAKCKbfNLeXKNuuCS98TD/7lRFRwtjACfZt3Y Y8R4j5o8A5bqalvEu3QR394= =zIPq -----END PGP SIGNATURE-----
