Yesterday my Macbook just hung, noticed a black screen and the beachball. Rebooted now I get that flashin folder icon with a question mark. Its stange, my HD told no tell tale signs of dying, no whizzing or strange noises. Anyway the problem is I'm travelling around the world, and foolishly did not pack my OSX starup disc. Any other suggestions, advice most welcome. I might just have to send the poor thing home Cheers.
