I had this issue once when the RTC XTAL was dead.

Yours is being protected/surrounded by some black plastic.

Yep, I see it...
Is there any easy way to test it without an oscope?

Maybe you have a multimeter with a frequency counter? But it must at least be able to read the 32.768 kHz frequency. I'm not sure if the cheaper ones go this high. And it's still a long shot.
Maybe you can solder one off from a donor board.

The power supply comes up fine on the PSU tester and I've tried two other PSUs, so it isn't that.

Honestly once we caught the oops of the RD-RAM (Let's me know how long its been since I've dealt with it) and we correctly ID'd the board\CPU I thought we were there...

I feel comfortable that we are down to a component issue so I'll add it to the "mess with later" stack.

It is disappointing because I like the board.

On a side note it continues to amaze me the amount of old-school knowledge available (back before you just replaced everything) and the willingness to assist on this board.

Thanks to everyone!

Specs: P4 1.6\256

There are at least 11 different P4 1.6/256 CPUs, there should be the S-Spec on the package, they are usually 5 letters/numbers, for your CPU it should start with SL, what it it?

If it's a stepping E0 then a BIOS update may be needed, but I would expect the CPU and GPU fans to start spinning even if the system won't post, if they doesn't there is likely some sort of power issue.
