Hi, I have a 24" LED cinema display hooked up to a quad 2.66 Mac Pro. Whenever I load Windows 7, there is a single 'pop' sound that comes from the cinema display's speakers. It occurs right after choosing the windows partition in the boot menu. Also, it doesnt occur if I disconnect the cinema display's USB cable. However, this sometimes causes Windows not to recognize the monitor. This sound never happens when loading the OSX partition. Has anyone else experienced this? Is there any solution to this? Thanks in advance!
