AFter a long break I tried to switch on my white emac this afternoon and it rewarded me with a grey screen and a tiny central square folder flashing an alternate question mark and apple smiley face. I can't get anything else at all, I have even turned off at the mains. Can't think what else to do, but feel this might be a reward for using a microsoft laptop for the past 12 months. Any solutions/suggestions anyone? Many thanks
