Hi there,  when I try to boot up my macbook pro the screen goes fuzzy with little checked marks across the entire screen.  I've removed the battery and done numerous restarts, no luck.  Is there a way of rebooting from the keyboard after powering up?



MacBook Pro, Mac OS X (10.7.5)

    Hi nbar,


    I don't know what MBP.  No there hasn't been any recent system mods done.  I will try your recommendations and report back.  Many thanks, G
