I went to restart my Toshiba Satellite C55-A and it won't come back on beyond the initial screen that says "Toshiba, Leading Innovation" and the little spinning loading wheel is only partially on and stalled. Occasionally it will say at the bottom of the same screen "Preparing Automatic Repair" but does nothing at all. What can I do to regain my laptop? Don't believe I have a reboot disc.Help! Lol Thanks very much.
