Ok, so a few days ago, while surfing the internet with Safari in OS 10.4.3, with an airport extreme card on my iBook G4 (trying to give you as much information and still make it a complete sentence, hehe!), I noticed a squeaking sound coming somewhere within the computer. I thought it was the hard drive at first; but it couldn't be, since I could open any file or application and this squeaky sound wouldn't happen. It's a rather quiet, yet high pitched, sound. Also, I have been loading webpages in other browsers just fine, browsers such as FireFox, Netscape, and IE. (I've got a bunch...it's almost like my browser farm or something.) So, I would assume that this is the airport card squeaking, since it only happens while webpages load...but I am not sure what is going on, since this only happens while I am using Safari. Any ideas?
