I had almost the exact same thing a year ago and ultimately it would not boot at all (no chime, nothing). From what I understand, if it doesn't chime, it didn't pass the POST routine on the motherboard.
You are right on, it turned out that the graphics card had burned out. I took it as an opportunity to upgrade to the 3870 radeon card which was crazily expensive versus what you get in the PC world but you gotta pay for no driver issues someway!
