[QUOTE="Penelope8, post: 1456943, member: 276112"] Thank you all for your collective help; this has been the best source of reliable, intelligent information for me. I have taken a few days' break from thinking about my sick iMac, but I got back to work on it this morning. I ran the Onyx software last week as recommended, and the startup time was immediately improved to less than 30 seconds. I was thrilled! However, the performance itself was still the same. Today, I downloaded, installed and ran the SMART Utility as lifeisabeach recommended, which indicated the HD was failing. So, I guess that was the issue after all. Big bummer, but I'm glad to know the source of the problem for sure. Now, I'm wondering why exactly is this HD failing and whether there was anything I could have done to cause it or to prevent it? Would the fan issue cause the HD to fail (and so quickly)? Is there any possibility the iMac itself has a problem? We used to frequently transport this iMac for display at shows (once a week, to and from home, in the original box with styrofoam padding and in the trunk), but we stopped doing this in June. Is there a possibility something has been jostled or jarred that would cause damage to the HD in this manner? Thank you so much for all your help! [/QUOTE]
