Iâm not sure if anyone can help, but here goes. My laptop has started playing up when playing DVDâs, the sound track runs ok but the picture plays intermittently, ie frozen picture but perfect sound. I have tried using task manager to switch off Processes not required (apple, Ipod etc), some times this will provide a temporary cure other times not. When the picture freezes the CPU usage peaks at 100 %. The laptop is only a 18 month old ACER. Any suggestions will be gratefully received.
