why does my iMac keep freezing?

This is a problem I've been having for some time, I have actually posted in the Intel iMac forum but I think the inclusion of Vectorworks has put people off.


Essentially my 24" iMac periodically freezes. I have looked in the crash log but it's not actually crashing as such so there is not always an entry there for a date relating to the freeze.


Is there a specific log for freezing or hanging up?

Mac OS X (10.5.8), Imac 24" 2.16GHz 3GB SDRAM, 2TB Time Capsule, 500GB LaCie Rikkik

Hello,


Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.


First, Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.

I didn't think I had syncing on, I do have an iPhone 4 but whenever I get the message asking if I want to sync i select no.


iDisc is showing in the side bar under my HD but I don't use it, I'm not sure if it's enabled or not.


The report is not from Safe Mode. Maybe I should try working in Safe Mode for an hour or so?


thanks

"Open the System Preferences panel, under Internet & Network clicked on .Mac icon, selected iDisk, under iDisk Syncing On click "Stop". Waiting for a while then clicked "Start".


I assume you had/have a .mac/.me account at one time?


If so, go to System Preferences>.Mac and remove your username and password.


Unmount any iDisk you may have.


If it should fail to dismount then, (Yeah crazy deal), either reboot, or open Terminal & paste in this exact line...


sudo umount -f iDisk/


It'll ask you for an Admin password that won't be echoed, but hit enter/return anyway.

why does my iMac keep freezing?
