Hi,
I got a free computer from my work. It was completely erased, nothing on it. Bought the OS 10 and I am trying to install it but I get stopped by a message about unsupported video configuration. The model is optiplex 990. This is the message I get: " this computer has an add-in graphics card, but the monitor cable is not lugged into the integrated video connector. To attach the monitor cable to the add-in graphics cards:
Shut down computer
Plug monitor cable into add in graphics card connector ( this may require a video adapter or video adapter cable
Turn on the computer.
I have all cables, only one monitor, what is the issue here? Can anyone help?
