Hi all Anyone else experiencing random screen flashing/blinking? it only happens when im using the 9400m. The first time i rang support i was told to do a hardware reset (hold cmd alt p+r) and this seemed to solve the problem for a couple of days but now its started again. Phoned up again and i've now got to take it in for a genius to look at. Im guessing this is hardware related and not much will be able to happen at the genius bar? Anyone know what my possible options will be?
