Sorry for the double-post, but I did try to replace the monitor- my computer with another monitor, and I got the same response. So once again, I'm back to square one. Now that I know that the monitor isn't the problem, do I have to remove the graphics card? I want an answer before I try it because it was a lot of trouble to install it and would like to continue using it...
Edit: I changed the monitor cable to the slot not connected to the graphics card, and it works. Thanks. Graphic card never was much use, so might as not find the source of the problem.
Edit two: I have another concern, for those inclined to continue helping me. So, let me explain it. Before installing my graphics card, none of the audio on my computer worked. After installing it, it then began to work. So now that I am using the computer without the graphics card, the sound does not work anymore. Anyone have a solution or know how I can use my old graphic card again?
