Jun 4, 2015 6:19 PMby 3DinteractiveICT,Thank you for that information.. Seems logical. I just wanted to run a test since for some strange reason, I am getting Pink Lines going down, in Safe Mode but in Normal Mode the entire system locks up with lots of little pink spots.. Its working fine right now but out of the blue it will lock up with the Pink Spots.. I have a feeling that its the graphic card is on its way out, but I cannot buy a new one.. Apple have made my iMac Vintage.. I have a new iMac Retina on order but I will sure miss this iMac. I was hoping to just use it for Windows for the rare times I use it and to pass onto our little girl to use.. Real shame.. Not a scratch or mark on it.. It looks new.. How can I throw it away...
Destiny..
