that came with your iMac.
I have brought my iMAC on Sept. 2010. it is the 27inch i5 core processor one.
However, just recently, my iMac has a serious problem
Here is the problem:
After I press the power button, the screen is showing the apple logo and the spinning circle(hope you guys know what I am talking about) and the gray bar under the circle. However, it is staying like this forever....more than 4 hours.
I have tried the hardware test that installed in MAC. However, the test is unsuccessful that the computer was freezing while the test was still going.
I am not sure whats wrong with my MAC.
Really appreciate if you guys can help me on this!!
