"1) Run Disk Utility --> Repair Permissions
2) Reboot your system, with the left shift key down. This will force the system to do a safe boot, and to rebuild your drivers cache and force a rescan of your hardware.

Safe Mode Documentation

If neither of those work, shut down, remove your battery & AC Cord, hold down the power button for approx. 5-7 seconds. Replace the battery, and plug in your AC. Boot up, and test again...

After all this, then maybe, it's time to Archive & Install... But first, check System Profiler to ensure that the iSight is visible under USB devices. If not, then it might be a hardware failure."
