Do you have another graphics card you could use? Or could you try plugging in a different monitor to your computer, or plugging your monitor into a different computer? We (well, you) should try to narrow things down to issolate the problem. Try to rule out the monitor, then rule out the graphics card. My guess is that it's either one or the other.
Does your mother board support VGA (have a place in the back of the computer where you can plug the monitor into)? If so, then remove the graphics card and plug the monitor into the back of the mobo, and give it a whirl!
Let us know how you make out with this!
War produces veterans, wounded both physically and mentally. They have sacrificed for us.....and it is now our job to help these veterans, as they have already helped us in ways we will never know, in ways that we cannot fathom, and in ways that we take granted every day.
