I have a 2007 intel iMac with a 2.4 Ghz Core 2 Duo, 750 gb hard drive (430 gb free) and 3 gb Ram. I am running OS X 10.8.2 and until 2 -3 weeks ago was still very quick. Now starting up my iMac is a pain, I'll turn it on and walk away because it takes so long to boot. Once it does start everything I try to open at first gives me a "not responding" but if I wait long enough it will respond. When it started acting up I had not loaded anything new. I have tried resetting pRam, SMC, used DU from start up and I have no errors on my smart drive and I have repaired disk and disk premission. From the Activity Monitor I do not have any "page outs" but 2.36 gb ram out of my 3 gb is used. My "Eye TV" program is suing the most ram @ 1.2 %, so I do not see any drain there. I have tried the purge, in "Termanal" to clear my ram to no avail.

Can anyone help please?

iMac, OS X Mountain Lion (10.8.2), 3 gb ram, 750gb hd

    I had the same problem with my iMac. I just upgraded the RAM and it was back to the speeds it got when it was a couple months old! has some great guides on fixing/upgrading computers.

    It's likely that your boot drive is failing, or that you have some other hardware fault. Back up all data immediately, then run the Apple Hardware Test.

    Make a "Genius" appointment at an Apple Store to have the machine tested.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.

    *An SSD doesn't need to be zeroed.
