My (early 2008) MacBook Pro will no longer start-up. The other morning when i tried to start it, i had to hold the power button down...when i let it go, it would stop. When i held it down longer, the superdrive made the usual noise it makes when you boot it up....then the front white led would start blinking rapidly then stop and computer stopped trying to boot up. any suggestions? i tried to reset the PRAM already and that didn't seem to do anything.

I had my MacBook Pro in my backpack last night and it got slightly rained on, but it didn't seem like it got wet....

Here is a link to a short video of what it does http://www.youtube.com/watch?v=1jK94oishaU&sns=em. I'm thinking I'm screwed, but a chance in hell is still a chance
