Dell XPS One 2710 brought to me to take a look. It's been restored to factory settings (Windows 8 with nothing added yet). I can hook it up as an external monitor (through HDMI) and it works fine. When I try to run as a computer, the screen remains black.
Pulled the hard drive and it works in another desktop. A different hard drive shows same results when installed in this computer.
Not sure where to go from here. Anyone have a similar experience?
Thanks!
