got up this morning and when I fired up my mac pro first generation screen has a heavy blue tint,thought it might be a monitor,so I switched them out but also had it on the 2nd one could this be a ram problem? I’m going to take ram out and reinstall but have no clue why this is happening,any help here please send me an answer to Rick email is trekman4780@att.net.
Hey, Have you tried a different display cables? If not then a different OS (run one off a usb). If not, then it could probably be a GPU problem, as if the ram is faulty/missing it will not show any image at all
