beeping generally means that it's getting part of the way thru the POST but not far enough to get anything on the screen.
you should have nothing connected except a known good video card, using your roommate's RAM is good, reseating the CPU and power may be needed too.

short of getting something on the screen, beeping is good. some mobos beep a number of times depending on the problem, but i don't know if this is one of them.
