Hey all, greetings from Greece I'm having a problem with my new iMac. Here's the story... I bought a week ago an iMac 20" MB323 from a local store that had it as bad stock. The Mac was/is completely new, i did the unboxing and everything was perfectly packed. I'm using it for 7-8 days now, and suddenly a strange buzzing sound came on. The iMac stands there in my desk and a really annoying buzzing sound appears. When I shut down the sound goes away, when I boot up the sound starts even from the white screen! And it's there all the time! It's drives me nuts! It's like having a mobile phone in vibration! when I gently lift the imac from the desk (even a cm!) the sound goes away! I've tested the screen illumination going up and down all the time! Does any of you have any idea what's wrong? I do now that the scene now is with the new iMacs and all of you are actually focusing on them but plz if you have any ideas help!
