Hi - Acer Asprie 7720G - When I leave the computer off overnight and switch it on in the morning it locks up, usually at a black screen with flashing cursor or at the Acer screen. I have to hold down the 'on' (power) button for eight seconds to turn if off. Then it starts normally. Any ideas please?
