The cold boot issues I am experiencing are different. After the computer is shut down (with PSU still on) I only get a brief flash when trying to turn it on. After that I have to turn off the PSU, wait 10 seconds, and turn it on.

Try disconnecting all but the CPU fan off the fan headers, and let me know if it helps. There could be plenty of things causing this kind of problem, but it appears from your description it's power related. It could be something as simple as the VRM overdrawing current on the 8pin ATX for a brief instant when you power cycle.
