I have the following iMac: 24", late 2006, 2,33GHz Intel Core 2 Duo, 3 GB 667 MHz DDR2 SDRAM running Mac OS Lion 10.7.3. (new HD fitted 1 year ago)

 

For some timeI I have endured 'frozen' applications, particularly the native applications Mail and Safari. I re-installed Lion recently but there has been no improvement. At prresent I am lucky if I can run Mail for more than 3 minutes without the system freezing (quitting the application doesn't really help, but a re-start will briefly).

 

My question is this: is my iMac just too old; is this a software or hardware issue; should I consider erasing the disk and starting again...?

    Repair/verify your drives with Disk Utility on your installer DVD.

     

    Run Apple Hardware Test from your 2nd installer DVD.  Maybe include the extended memory tests.

     

    You may be able to do these operations from your recovery partition with Lion.

    Found and ran Apple Hardware Test: all clear though the extended test locked up twice before completeing.

     

    Locked up?

     

    Try running Rember and see what happens with it.

    Interesting you suggest loading Rember as the last software I was recommneded on here was MacKeeper!

     

    Huh?

     

    I hope you didn't install MacKeeper.

    Probably not, I didn't see the capacity of your HD noted and how much is currently being used. OS X tends to like a minimum of 10-15% of the HD available. If you are not sure how to check locate the HD in Finder's sidebar, highlight it and type Command I (I as Ivan) and you will see a graphic similar to:

    If the HD is the original it also may be failing, in Disk Utilitly look for it's S.M.A.R.T. status. It should indicate Verfified, if it says anything else then it's in trouble.

    You have plenty of HD space. To check it's health you should run Apple Hardware Test in Extended Mode. If no errors appear after the first pass (30-60 minutes) run it another 2--3 times, AHT doesn't always pick up errors so you should  run it multiple times to be sure.

    That has already been done.  If Apple Hardware Test (AHT)locks up when there is nothing attached besides Apple keyboard and mouse, that means there is a hardware issue with the machine that only Apple can look into, except for possible RAM failure*:

    RAM failures do not always show up with Rember or AHT, but if they do, they are believable.
