Hi all, My mom's 2008 iMac with Yosemite and 4 GB RAM will no longer start. (Sorry that I don't more specs, but it won't start) When I push the power button, all I hear is a clicking sound near the optical drive. No startup chime.
What I have tried: If I unplug the machine, and remove the two 2GB RAM cards and then try to start, I get the "no RAM present" tone. If I then unplug it, put one of the RAM cards in, and then push the power button, I hear the startup chime, but the screen is dark. I have tried booting from a flash drive with Yosemite, and booting from the AHT disk, but to no avail. The same thing happened last week, and I kept swapping RAM cards out with some old 1 GB RAM cards from a previous machine. Somehow, it eventually started and the screen came on. I was able to run the Apple Hardware Test, which gave this error: 4MOT/2/40000004:HDD -1392, and a subsequent running of the AHT gave the same error, with -1384 at the end. After searching the internet, some folks said that the error was a HD fan error. Some suggesting vacuuming as much dust out as possible, which I did. Then I ran the AHT again, and it found no errors. I also ran Disk Utility, which found and corrected permissions errors. It did not indicate other problems. The machine worked fine for about a week, but today when I tried to wake it, I got a black and white checked screen. I had to force it to shut down, and now it will not start again. I get the same clicking sound near the optical drive. However, if I pull out one of the RAM cards, I can get a startup chime, but I still have a black screen. Any thoughts on this issue, or how to troubleshoot it? Thanks! Joe -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
