problem? Whenever I use an app or the iPhoto this always comes out "no camera is connected"

Bluetooth: not available

Whenever I press F5 and F6 to adjust the brightness of the key board light, it doesnt work either.

WHAT THE HELL IS WRONG WITH MY MAC?
..and yes, they worked before. I tried upgrading my software to snow leopard but it dint finish. So, what should I do?
