How full is your HD Iain? You should always have at least 20% free, because the OS uses vast amounts of HD space for virtual RAM. If the HD is getting full it will impact badly on the overall performance.

Replacing the HD on an iMac is easy enough. Suggest a WD Black 1Tb?

Ram won't make that much difference but try checking the permissions, go to Disk utility and Select your main HD then Repair Permissions.

Best to do it when started up from CD.

PM or eMail me if you like.
