I had a similar experience with a ECS motherboard. In my situation, there is
a bios entry related to choosing the default display that was set to the
PCI-E video by default rather than the onboard video. It did respond to an
old PCI video card that let me set the default to the onboard card. 

I do have a question, though. You mentioned the 'font light' that I think
you're talking about the power light. Does the HDD light do anything? Or is
this a new hard drive with no OS to trigger hard drive activity? I had a
different ECS motherboard go bad on me under warranty that triggered the
power light and fans, but there was no activity from the hard drive or AGP
video.  This was one of the few times I was happy I'd bought the extended
warranty from Fry's.

Subject: [PCBUILD] No signal on screen, no beep sound after desktop
installation.

Anyone can help? 
   After installation Motherboard Gigabyte GA-M78GM-US2H and AMD Phenom X4
9750 4MB Socket AM2+ CPU, 4GB Corsair memory PC6400, IDE HDD 200GB, CD-rom
(I followed step by step the instruction properly). I turned it on, there
was nothing on the screen, no beep sound...but the CPU fan and system fan,
font light were running, that mean power is ok. After many tries plug in and
out all other components, I was so frustrated. I don't to return them, it
would be more hassle. 
   So, anyone can help me with this issue. I really appreciate.
Thank you.
