Testing a bad mobo/CPU/power-supply?

[KENNEDY_KEIT-ROuZJvFXBa6Vc3sceRu5cw at public.gmane.org (Kennedy, Keith)]

I have had this problem many times in the past.  If its ram, it would
usually issue a beep code, telling you that it is ram that is the
problem, with the cpu or motherboard as the problem, it would pretty
much do just as you've said.  At this point what you can do is try
swapping components.  I would be willing to say that it isn't video, but
if you have any video card lying around, just pop it in and that should
quickly narrow that one down.  The problem is your motherboard most
likely doesn't have an AGP port, and those cards are probably the most
common right now, and the most likely to be laying around.  Hopefully
you have a pci videocard lying around.  I doubt it is video, because on
some motherboards, you get a single beep from the POST routine to tell
you that everything is running fine.  This is dependent on having a
working speaker though.  Again, Newegg is probably the fastest way to
find out and the easiest if you don't have a bunch of components lying
around.  At this point, I would say try the ram in another machine and
RMA the board back to Newegg.

Yes..  And Yes.   There appears to be a small percentage of these mobo's
(according to reviews on NewEgg) that arrive DOA with no post beep or
anything.  I'm worried that I might be one of them, which means I have
to wait until next week to deal with this.  :(
