How can I renew the graphic-card on my iMac
If I start up my iMac it works but the screen is black. The
Apple-serviceman said that the graphic-card is bad and it would be about $ 1000,-- to fix it. The computer is only five years old so I want to do it by myselfe like I repair some of my old mac´s. How does it work? Who can help me?
