Screen pixelates, freezes then whole system crashes
Hi All,
My Imac screen starts to pixelate with flickering pixels around the screen at first, followed by the whole screen pixelating and freezing and the system crashes.
I bought my Imac in January 2010.
Any assistance greatly appreciated.
Regards,
Ian
