Cyclone III Programs, Doesn't Boot

I have two boards with Cyclone III FPGAs that appear to program and verify properly but it doesn't boot. It has activity LEDs that turn on, showing that it is doing something but not operating as it...

I used Quartus 12.1 to program with an Altera USB Blaster.

I forgot to mention that this problem is unique to these two boards.

I don't think programming setup it wrong because we have programmed many of these boards without issue. The two boards that I am looking at are outliers that I would like to get working.

Our customer did the design and firmware. We produce, program and test these boards.

Are there any signals that the FPGA needs to load and run the image from flash that isn't needed while programming?

I am mostly wondering about possible hardware issues with bad parts and bad connections.
