    I have an iMac and decided to update my softwares.
    It told me to restart, and once I did I saw it installing.
    After, my cousin accidently turned off my computer and now when I try to turn it on everything is normal until the apple logo changes into a gray stop sign.
    Can anybody help me?

    Your update was botched. Insert your computer's restore disk and boot to disk by holding C at startup. Set the installer to archive & install, and select preserve users and network settings. When you're back up and running, run Software Update a few times and you'll be good to go.
