Multiple flickering pixels on display flashing purple and green
iMac i7 16g-RAM ATI 5750 1024 Serial ending 1DNR, OS 10.9.1 Multiple pixels flashing purple or green. Is this a Logic Board Fail? Is there a BIOS fix for the graphic card? I hate to spend $1,600 to replace a logic board.
iMac (27-inch Mid 2010), Mac OS X (10.7.3)
