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.

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? 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.

If you can start up in windows, get Mac Drive, just the trial is all you need. It lets you see the Mac OS file system. Then you can retrieve the files through that. Unfortunately I have no idea how to fix the problem, I had it happen to me once too, I just grabbed everything important and put it on an external and then reinstalled Mac OS and it was fixed.

Zap the PRAM, it does nothing bad [except get rid of a few settings stored in it, but they're easy to put back to the way they were].

Also, your video card may be failing, which means the zap may have done nothing useful.
