My 15inch Macbook Pro wont switch back on

After my MacBook pro crashed during an update, I switched off and restarted. I get the apple logo, and the progress bar runs to about 3/4 the length of the bar, then the machine just shuts down again. I have repeated this at least 20 times now. Any advice much appreciated.
