I'm hovering between the MBP and Windows forums here (it seems to be a hardware problem but only happens in Windows)... When in Vista (using Boot Camp) on my 2.33 GHz C2D MBP, the system intermittently emits a high-pitched squeal. I don't know whether this is the infamous "whine" (I thought that was fixed in the C2D systems) but it's definitely making a noise! Has anyone else experienced this? It's only happening in Windows, not in OS X.
