Hi everyone. I have an early 2009 iMac that's now running really slowly. It freezes all the time. I'm only guessing but I think it's time for me to add RAM to it. I've only used half of my hard drive space, so that can't be the issue. Would additional RAM be the answer? If it is, what kind of RAM or what brand or how much RAM do I buy? I've never done this before so any advice you can give would be really helpful. And nothing too technical please. I've attached some pics of specs that I thought might be helpful. Thanks muchly!
