Hello, I built my own desktop and have been running with one monitor for awhile with no issues. So i decided to get another monitor so I can run a dual monitor setup. I plug my new monitor into my graphics card which is a (HD Radeon 7970) and I plug my old monitor into the video card using an VGA to DVI adapter. I start my computer up and only my new monitor is working. I went to display options and say that the second monitor isn't detected. I tried detecting it and nothing. I have Windows 7 and an i7 3770k processor.
