Hi
My acer aspire 7540g laptop is displaying vertical column of stranges lines down the middle of the after about 20mins of watching a DVD or playing a game.
The GFX card is a ATI Mobility HD 4570. I originally thought it was a driver issuse so I updated the drivers from the ATI website but alas it is still having the same problem. The weird thing is that the lines dont display on an external monitor only on the laptop screen.
The laptop base isnt hot either so I dont think its overheating etc
Any one have any ideas what it might be?
