I have an Early 24" 2009 iMac. 2.93 Ghz Intel Core 2 Duo, 8Gb 1067 MHz DDR3, NVIDIA GeForce GT 130 512 MB Graphics card. The display is nice and bright, is quite fast, but... It shuts down randomly. I'm quite sure it's the graphics card, or, a slim chance it's the power supply. I've replaced it with a new iMac so I have no interest in putting money into fixing it. I could fix it myself by buying the parts, about $180 for graphics card, $90 for power supply, but I don't need it now because I have a new iMac. But, I'm having a hard time throwing out my once $2200 iMac. I'd be more than happy to give it away. Is it truly just junk and should I take it out to the trash?
