    For some reason my Macbook Pro 15' inch won't start up. It's stuck at the blue loading screen after the gray Apple. The screen switches from two blue colors every 5 seconds or so along with a loading symbol. Sometimes I can see my mouse and use it, but that's all what is happening.

    The last thing I did was installing the newest video driver on my Boot Camp. (Windows 7 - 32bit and Leopard 10.5 for mac)
    I can still start up Windows 7 without a problem on Boot Camp, so it doesn't seems a hardware issue.

    I already tried some stuff found on the internet, but I can't start up 10.5 in normal or safe mode.

    Anyone here knows what is going on with my mac and can help me to fix it?
