The use of the word "iSight" that I have seen associated with "pc" means the long-discontinued Apple webcam hardware that looks like this:
(1) Are you using a PC; i.e., not using a Mac? Tell us what specific computer model & OS you are using.
(2) Did you simply unplug your old iSight cam, or did you do something else such as erase the iSight driver software from the Windows® or Linux operating system software on your PC or perhaps remove your PC's Firewire expansion card?
