I bought a Mid 2011 i7 imac 3 years ago, and from what it looks like a power surge fried most of its components (I've tried every trick I fould find on the web. It wont turn on!) Once in a while the fans will start running at full speed but thats it, no video, no sound. Nothing. Apple told me they could fix it for +$1000, they have to replace the power supply, logic board and even the back casing. you think it'd be a good idea to do this.or should i just get something new? I loved my imac
