    Hi all,
    I'm doing some general technical stuff for a company as a freelancer but this is a little outside my normal field of expertise.
    Unfortunately nobody currently working in the place knows much about the equipment and all the previous technical staff are gone, so I am doing a bit of detective work as well as maintenance...

    There is an early 2009 Mac Pro that was believed to be broken. Initially I got no chime on startup and no video signal, but I could hear the boot drive working. I reset the PRAM and got 2 chimes!.. I still got no video signal though. I've now logged in without a display and am now connected with another system by screen sharing.

    Attached is a screenshot of the Graphics/Displays readout in System Profiler.

    I literally have no idea what the problem is, or what to read into that readout lol.

    Any help or clues would be much appreciated if anyone knows what might be the prob or what I could try..
