I purchased a new iMac for Christmas.
I have used it almost daily since then.
All of a sudden I have been receiving a sometimes quiet, but sometimes loud ticking noise coming from the behind/underside of the computer. Nonetheless the noise is prominent.
I have read a few articles on the web, some claiming it is a noise that suggests HDD failure, other suggesting that it could be a loose wire being slightly hit by the CPU fan as it rotates.
I downloaded smcFanControl and played around with the speed of the fans and it made no difference. I then called Apple Support and they took me through a few steps to reset the power supply, or something. It involved unplugged, starting up again whilst pressing cmd, alt, p, and r and a few other steps.
I am just wondering if anyone has encountered this position before and/or if anyone has a solution.
I am running OS X Lion version 10.7.3
Many thanks.
(PS: I will be able to upload a video of the noise, if need be.)
