I don't see any LEDs on the mainboard. There is one light set in the front
of the case that goes to amber. Another box of the same make and is still
running has the light off.

It's already down to a single stick that was working. I will have to try
with RAM from elsewhere.

I thought of that last night, so left the box turned off for the evening.
After running for a while today ( waiting on it again ) the heatsink
didn't get very warm.

The box had been up and running for several days, including several
reboots.
