Hi, I looked at the video and it's not a whole lot to go on. If I understand your issue right about the optical drive why don't you remove the top cover and just disconnect it from the logic board, then do a reboot. If you still have the same issue I would suggest that you remove the battery and the internal battery connector (the pram battery) from the logic board and just wait for about 10 minutes then reconnect everything and see what you get. If you get lucky I would immediately go ahead and reformat that hard drive and reinstall the Mac OSX system without the dual boot of Windows. If everything works out run a reburn-in process for the hard drive using the drive genius 3 disk via the firewire port for an external optical drive. Depending on the size of your disk, the amount of time to complete the process may take anywhere from 1-3 days. You have nothing to loose if you can get this far with it, if not then your logic board may be "going-up" on you.
