Question

Start-up of 27inch 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!!

Answer
You need a new HDD

You need a new HDD. The progress bar is a pretty good indicator of that. You only tend to see that if you're installing a SMC update or the HDD has crapped out, but not quite enough that you get the flashing question mark folder.

And if you bought the thing in September of last year, it should still be under limited warranty, so take it to the nearest AASP or Apple Store and make it their problem.

Thanks a lot

Hey thanks guys for your answering.... so you guy reckon that there are high possiblity to be the problem of HD eh...

I actually jst want to ensure it is a hardware failure since it is still under warrenty.............

I jst dont really want to pay the cost sicne I have called AASP and they say if they found out is software problem they gonna charge me............

is ther any way to determine whether it is a software problem..........? like reinstall the programme?

Re: how to determine if it's a hardware issue

Diagnostics (as you did) seem a fine way. Trying to reinstall the OS should work also.

I can tell you

I can tell you that I work as a hardware tech fixing Apple systems, I just don't work for Apple. I do maybe 25-30 systems a week on average, and have kept that pace for probably the last 6-8 months. That smacks of a HDD failure, plain and simple. But AHT is pretty much worthless for finding anything beyond obvious errors, so it'd be worth it to have someone be able to run the big boy tools on it.

cheers

Hey thanks for the replying!! very appreciate.....Jst confirm once again........so you think it must be the Hard disk failure?

Also feel the same as well, AHT tells me nothing though since it was freezing in the middle of the test.............XD
