[QUOTE="techiesteve, post: 1922629, member: 98520"] From long ago the graphics cards had known issues and failures were originally covered by Apple under a quality program. Displays and optical drives often have issues now due to the age of these iMac's. When these iMac's became vintage and spares were no longer available from Apple it was possible to get the GPU chip replaced, then the chips ran out. Then substitutes were fitted that required the temperature sensor moving from the optical drive to the graphics card as they ran hotter. Some customers had the BGA GPU chip reflowed, but if that worked it didn't last long. I would be wary spending money and effort on one of these iMac's. [/QUOTE]
