How can I get rid of grey lines on my iMac Display?
I have grey lines at the bottom of my screen they get thinner and disappear as they get higher on the screen these were flashing but I completed all the advice on resetting graphic card and reinstalling OS
It has stopped flashing however feint lines remain does anyone have a definitive on what the problem is
I have installed HOT but it is not due to overheating as normally sits at around 40 -45c
