[QUOTE="Penelope8, post: 1455217, member: 276112"] Wow, you guys are great help! vansmith, nothing appears to be using more than 6% of the CPU at any given time. lifeisabeach, we chose not to use another seagate drive because of the reputation for failure they seem to have. the guy who replaced it had no input on that decision, but he said the fan not turning off wouldn't be a problem. I'm sorry I was unclear before in describing the activity of the comp. Previously, the iMac would just get really long delays in anything I did. Opening a Finder window would take 30 seconds. Transferring one small file to the desktop would take a minute. I couldn't get cmd+tab to do anything, nor cmd-opt-esc. Everything was stuck. Sometimes if I waited long enough, it would catch up to me, but usually it was pretty much unresponsive. I used disk utility to determine that the HD was failing, and immediately backed up everything I could before it crashed completely. I really had already backed up everything important, but the tech guy who replaced my HD was able to recover data from my old HD, just to make sure. The Apple counter folks couldn't do data recovery, and refused to surrender the old HD when replacing, which is why we opted to go an independent route. I'm not getting the significant lag I was getting before in performance, but it seems that the comp is getting bogged down in some task (no clue what) and has to think a lot (with the SBBOD of course) before catching up. When it's "caught up" to me, it seems to be fine, performing as usual. It's very frustrating to get stuck for 30 seconds to a minute at a time, though, sometimes occurring every two minutes, sometimes not for an hour. I thought the issue was Firefox, so I removed Firefox. The comp was better for a day or so, but now continues to get stuck. I have not installed any anti-virus or cleaning software nor MacKeeper. I have Mac OS X 10.6.8. I don't know how to tell the year, but I believe we purchased it in late 2010 (brand new). pigoo3/nick - I try to always put it to sleep or shutdown when I leave the computer. I have to leave it running sometimes when it is performing a large transfer of files or other long activity, often overnight. I would estimate that I put to sleep about 60% of the time I leave it, leave it running about 20% and shut it down completely about 20%.
