Hey friends! I bought a Imac begin 2008 for around 125 dollar with the mission to repair this thing and save me some money! its a 2.66 ghz with 320GB. He already has new power and a new hard drive (changed by the seller) description : Imac powers on and start to install snow leopard, everything is working ( sound,screen,keyboard,mouse,... ) after 5 minutes the Imac shuts down and that's it. As you already can figure out from this post I'm a noob at this. My question for you, what are my chances to get this thing working if a buy a second hand working logic board?
