On a related question to this one, now I have a file server whose power supply and fans spin up, but gets no video and no beep codes.
I have tried two different video cards in the system, and neither one sends any signal to the monitor. The monitor is a known good one; just borrowed it from a working server. The system does not have any hard drives connected to it -- just a power supply, motherboard, CPU, CPU fans, full memory, and the video card.
I've tried the obvious "swap the cards" trick. Are there any other reasons I can troubleshoot for dead video? CMOS? Memory?
