Hey, I just installed iDeneb v1.4 10.5.6 on my PC (which I've checked and is compatible apparently). The installation went fine, once done I rebooted and the grey apple logo screen appears and it gets stuck there. I think it could be my graphics card (Nvidia 8800 GTS), but have never used this OS before so have no idea what to do.

Anyone got any ideas? Cheers.
