Guys, I've seen a few posts in the net...and I think it can be resolved with a reinstall (hope so). But what I need to know is...can a white screen with Apple logo be an issue of the graphic card ! As to my understanding, a stuck Apple logo can't be an issue of the graphic card .....or is there a possibility? I am thinking of purchasing this faulty iMac 2008 and was told by the lady owner that a technician told her that it was a GC issue. Any of u guys HV come across such a GC issue ?
