I am having the identical problems with a P4, 1gb ram and a 17" display, I have tried all the posts on how to fix the problem, to no avail. I just get a black screen. HOWEVER, today when booting I can see my curser blinking on the upper left of the screen, and it moves straight down 4 lines. No other things happening.
