My MacBook Pro specs are in my sig. It's been running perfectly until 1 hour ago. This is what happened. I had to restart my computer because I was gonna boot into windows. Now the whitescreen screen is gone. When I boot, all I see is a black screen but the display is still on and hear the Apple startup sound and that's it. I can't even do the reset PRAM thing. Also, the bottom gets very hot. Anyone have suggestions. The only upgrade I have done was the ram back in April.
