I had one. It was given to me because of the screen freezing. It ended up being the video card. I tore it down , cleaned the heatsink and applied artic silver andl upped the fan speeds and it worked fine.

I ended up selling it because i didn't have a use for it.I tried giving it to everyone in my family but they were all afraid of using a Mac. I got 400 for it last year at a place in Greensburg , Pa.(cyber depot)
