Tom,

The computers were originally networked. We have had them apart now, and I
find I am able to fire up the power supplies by connecting pin 14 to pin 15
on the ATX Power supply connectors. The machines still will not boot at all.
There is no post, and the ONLY LED that lights is the one mounted on the
mother board. We have come to the conclusion that we have all eight mother
boards dead. The machines do not turn on any of the front panel lights at
all.

If the machines would work at all, we could reinstall the OS, but with no
response at all, we are dead in the water.

When I got the power supply working on Saturday, a quick check told me I had
proper power from all leads, but still a dead board. When checked, the Power
On lead had 4 volts, but when connected to a ground lead, the power supply
immediately came alive. Still no lights on the front panel, no post. The CPU
fan started running immediately. Nothing else I could see.

 What could possibly cause that, and in multiple machines? What are the
possibilities of a run of bad mother boards?

Another congregation member has taken one of the units to his home to
troubleshoot. He deals with a lot of hardware issues at his place of work,
and finds the exact same thing. This is miles away, so I highly doubt the
power source. (We do have the server in the same room, and it runs properly.
However, it is powered by an AT type power supply.)

He finds the power supplies are fine, but the mother boards are dead.
