Faulty IBM ThinkCentre A52 displaying no video

I have a Small Form Factor IBM ThinkCentre A52.  The problem I'm having is that the machine will not display any video.  When the machine is powered on the fans run but that's it.  I've swapped everything but the case and even with a new motherboard I get the same problem.  Additionally, I've tried different power outlets, different monitors, keyboard and mouse.

When I say swapped everything I mean just that, ram, PSU, CPU, mobo, etc.  Thanks in advance.

What i would do is connect the parts to make a working computer then swap the parts from the one you are trying to repair to identify the bad component(s).

Have you tried swapping the monitor?  A motherboard swap would mean you are replacing the video card and the motherboard, and that is usually where these problems start.  You might also have more than one problem part, but try a different monitor first.

Tried another board, monitor, cpu, ram, psu, disconnected, optical drive, hard drive, floppy, etc.  There is always the chance that the replacement board has the same problem.

With nothing attached to the motherboard, ram, cpu, fans PSU, I get nothing for video.  Happens on both boards.

First, reset the CMOS and try again.  Then try the motherboard outside the case, sitting on a cardboard box.  This will eliminate any grounding on the case.  If the symptoms remain, I would be inclined to think you have a defective motherboard.
