IIRC, the NVRAM card should only flash for about 1 sec and then both lights
should go steady until the PROM gets to the RAM test (the last thing it
does)

    I'll take the TCE :)

    Try reseating the power connectors on the MB first. Are both of the
LED's on the CPU daughtercard on steadily? If they are I believe that
indicates that you have good 5V power. If they flash or flicker then you
most likely have a power supply problem. If they stay steady, then it's
likely to be limited to the 12V side of the PS. It does stink of a bad
filter capacitor (the large 300V ones).
