Serious Problem with Macbook Pro Screen!

[Insilencio]

Hi everyone, I have a big problem. Today, I noticed that my Macbook Pro was running a bit strangely, with some video being slow and stuff, so I restarted it while it was in Windows Vista through BootCamp. I came back about ten minutes later to see a black screen, and the computer still on. I don't know if it restarted or not. I tried hard resetting it countless times, and messing with the battery like letting it run dry and stuff, but whenever I keep turning it on, I hear the "dong" boot sound, but the screen doesn't turn on, ever. I just kept hard resetting, to no avail.

No I'm wondering if a PRAM zap will help fix the problem, but I really don't want to lose the hard drive and the stuff I have on it. I have a TON of school and work files on there that I simply cannot afford to lose. Will a PRAM zap kill my Windows Vista hard drive or should I even go ahead with it? Is this just a screen problem and how do I hook it onto an external monitor to check? I really hope that I can fix this problem myself, because the nearest Apple Store (and Geek Squad place that supports Macs) is over 40 miles away, and I really need the stuff for school on Tuesday. Please help!!! I thank you gratefully, everyone.

PRAM/NVRAM reset will not touch the data that you have saved on your hard drive.
For everything that one cannot lose, there should be a backup in place though - just in case. With any OS.
