Hey everyone, I purchased my iMac Dec. 26th,2009 (week 51). I don't have a yellow tinge, dead pixels, or flashing. However, I have discovered that sometimes my computer will start this weird tinking/clicking sound out of no where and I don't know how it starts to do so (like it isn't even overheating). The last time it started this noise was when it was on for about 2 hours and I had watched some TV episodes. I've already contacted Apple Care and they told me its something wrong with the hardware and I should take it back to the original store it was purchased at. Thing is I purchased it in Delaware but I live in Maryland. Now I'm going to go to Delaware this weekend but I'm not sure if I should even hassle to take it to the store because what if they don't hear what I experience and I just wasted my time? The noise is really loud when it comes on and it can be clearly heard when I tilt the computer all the way back. It sounds like its coming from the lower right corner but I'm not sure. At this point Apple Care knows all about the problems and they have expected me to get a new computer... I know that I could probably demand for a replacement but after that I won't be able to and who knows it could be worse.Plus, I can't leave it to them overnight because I have to go home for school and such... So what is my best option?
