I’m testing a Quadra 950 in the hope of adding it to my collection. But it makes a subtle squeaking noise (not from the speaker), and the internal video becomes distorted when it reads from the hard drive. If I push down the mouse button, for instance, to make a selection in the main menu in finder, it is almost like I can control the squeaking noise. If I use a Nubus graphics card, the video is fine, but the noise persists. On close inspection, the board looks very nice and clean. Has anyone here had a similar problem?
