It was suggested we get a DVI to ADC display adapter (M8661LL/B) to mate our monitor with this computer we have. I got the adapter and hooked up as shown in photos. When I turn on power the light above the on/off switch blinks and never stays continuous. If I press the on/off of the monitor, it glows orange when pressed but nothing else. There is no other action. The fans are running in the tower but nothing else.
