I took apart my iMac and only diagnostics LEDs 1 & 2 are solid green. 3 & 4 are off, so I'm assuming it's related to the graphics card, from what I read on this website. Where can I buy a replacement graphics card or is there anything else I can try before purchasing a new one? I have a high level of tech experience so working on it myself is not an issue. I just don't have many "Apple" years ; )
