IPhone froze at loading screen

So I was moving my icons, and suddenly, the phone froze. I wasn't able to click anything. I turned off the phone by holding the home button and the power button, and now it's starting, but it freezes at the apple logo. I connected it to the pc, its all like it was before, its downloading photos from it but the phone is frozen.
