Grey Apple, spinning circle, thin line down the screen.
I am working on my friend's older white Macbook. The computer makes the chime, has the grey screen, with the spinning circle, and a very thin white-ish line down the screen about two thirds of the way across from top to bottom.
I was told there is a bad hard drive, but I am not so sure about that. I have hooked the HDD up externally to my other computer with a universal drive adapter and tested it with the disk utility and the test passed.
What could be the problem?
Is this a good question?
