I just bought a new 19" LCD monitor which has DVI and VGA inputs. I connected the dvi cable to my old fx5200 and got nothing on screen, the monitor didn't even turn on. However I then hooked it up through VGA (on same fx5200) and everything works fine. Could the problem be the graphics card or is something wrong with the monitor?

Can you get a hold of another DVI cable? Sometimes cables in general can come defective, I doubt it's your DVI output.
