Does anyone know if apple are replacing graphics cards on Imac 27" i7's from 2011?
My windows keep going black on me but the background desktop is ok, the menu headings at the top seem to be in negative. I've have heard this model has had problems with the cards but can't seem to find any info on the apple site... can anyone help?
