My early 2008 3.? GHz intel imac began having issues with a flickering screen (lower half) the other day when in p'shop. It would freeze and the power button was the only way to escape.
Restart was normal and all else was okay…but it also flickered once in Safari.. but that did not freeze the computer. It only flickered and only that once. And days went by with lots of usage but every time I launched P'shop (might take a few minutes but) it would freeze. (Downloaded GIMP for emergency graphic work)
A friend suggested and believed that the memory might be the cause. He said I should remove one of the two sticks and see if the problem continued. I removed ONE stick.. still had some p'shop issues and so I exchanged sticks… powered back up and saw no great improvement.
Then when I replaced both sticks and powered up it will not get beyond the gray window. The 'gear' symbol makes about 40 rotations then stops. Frozen again.
I tried all the PRAM and Safe Start up modes AND I have started in Single User mode several times. I get the --Modifications Were Made-- line and run /sbin/fsck -fy until it says it's okay. reboot and it stops on the gray screen. Over and over.
I tried starting up from my OS X 10.5.4 Disc but it too freezes on the gray screen.
Is my memory the problem? (haven't any to substitute)
Was it okay to try to start with only ONE stick?
Spent hours researching without answers.. and Any help will be appreciated!!!!!!
