Ok so yes, the computer bongs whenever it boots up. I did that thing with the lights, and only lights #1 and #2 light up. Light #3 stays off as well as #4. So would this further prove my theory of a dead video card or would it mean something else? Are there some steps I should try in order to fix it? Oh yeah and the fan does turn on, the only thing that is wrong is that the display stays black.
