hmm....
Reset your PRAM first...no luck?
then, first pull out 1 of your sticks of RAM and see if it will boot...
if not, do you have any of the stock CD's to boot from?
Thanks for the suggestions. Here's everything I tried that hasn't worked:
1.) Reset SMC
2.) Reset PRAM
3.) Boot from recovery Lion partition
4.) Boot from recovery Leopard DVD
5.) Pull each ram stick and try to boot with just one
6.) Boot from a different internal hard drive
7.) Boot from an external USB drive
When I hold the Option key at boot, I'll get the drive list to boot from, but then after a selection, it shuts down like in the video.
I then just got back from the local Apple retail store. The Genius also did 1, 2, 3, and 7 with no luck. Their assessment is that it must be the logic board which would cost me $280.00 since it's out of warranty. I challenged them on why it would just all of the sudden stop working and they compared it to a car where things just fail. This is only 2+ years old! Apple products usually last a lot longer!
I just don't get how its working fine one night and then the next day nothing!
