    I have loved and cherished my MacBook Air for two years now, but last night it went in to a reboot cycle for no apparent reason.

    Now every time it gets to the apple logo i get the rotating "thinking" ident under the apple logo and it restarts........continually......i did the hardware test (holding down "D".....that was fine.) I also reset the PRAM... so the troubleshooting keystrokes woirk.

    I'm worried my hard disc is blown.

    Any ideas?

    Thanks

    restart holding down the 'command' + 'v' buttons (to kick it into verbose mode) so you can read the start-up sequence and see at what point it goes back to restart.

    my suggestion is to startup from an external drive containing Snow Leopard install disc whilst holding down the 'option' key and then reinstall the OS.

    that should fix the problem.

    (if it doesn't then it's off to the Apple technician and raid the piggy bank to pay for repairs - but a fresh install usually fixes most issues)

    let us know how you fare

    put in your leopard disc , hold c key , boot off cd

    repair the disk permissions under disk utility.

    see if that helps,

    if not, use tech tool deluxe and diagnose any problems.

    he can't - the Air does not have an internal drive; thus it'd take for the install dvd to be inserted into an external drive and hold down the option key to ensure the Air starts up (not 'boots' that is a PC word) from the dvd.

    that said, your point about repairing permissions first from that install dvd is a good one as a first remedy
