Hi, I have a 2006 iMac, 2.16 Ghz Intel Core 2 Duo, 1 GB Ram and over the years my computer has gotten considerably slower. I don't plan on upgrading the ram or taking it apart to change anything, but I do notice it get slower over time. I plan on either buying an iMac or just building a computer soon but I want to use the last bit of life I have left on this computer. I do a pretty good job of keeping the computer clean and wonder if there is anything else I could do to make it faster and and maybe let it last longer. I know the basics of keeping it clean but I was wondering if there is anything not as common that will help it. Is there anything I've missed about keeping a computer fast a clean?
