Hello, I recently obtained a 2008 (I think) model iMac (aluminum 2GHZ core2duo, 1GB ram, 250GB hdd) and when I power it on it goes to a grey screen with the apple logo and a "progress bar". I plugged in my Thermaltake USB gaming keyboard and tried to do the "shift+boot", "alt+boot" tricks but to no avail (the keyboard doesn't "light up" until well after the mac starts it's progresss bar thingy. I got this thing for free in a trade of my old blackbook macbook (I currently use a mid-2012 13" Macbook pro, and have a banging gaming desktop.) So I want to get this thing working 100% as a "guest" computer, or "studio" computer for my apartment. What should I do first? If the hard-drive is bork does this mean I need to pull the screen? Please help me, as the most I've even done is replace HDD's in My black macbook, and replace the ram in my MBP! Thanks! Iain Fixie.
