You know that electrical smell ... well that's what is coming from the cabinet in which I have my Mac. It's not pungent or burning, but it's there. It may just be the DSL modem that Verizon recently sent me because that did have an odor like that when we hooked it up. Most importantly though, the computer is making a whirring sound, almost like a heavy hum when it's turned on. As it runs it quiets down though. It isn't loud but it is noticeably there and it's been doing it for a long time. I'd say for about a year and nothing bad has happened .. yet. I'm just wondering if I should put any more money into it. It needs more RAM to put Tiger on it and run it more efficiently but that shouldn't be a problem. I just wonder if I should abandon ship or stick with it. It's been a great machine and isn't beat up at all. I've rarely used it over the years. I'm new to the forums and all so any help or suggestions would be greatly appreciated. Thanks!
