This system has been up and running for over a year.
I turned it off to go on a trip and when I returned it wouldn't boot the first time - but it did the next time.
Recently I went on a trip again and now it won't boot:
No beep codes.
Video monitor light goes green briefly then back to yellow.
Removed the RAM - still no beep codes.
Reset the CMOS - still no beep codes.
Have 2 sets of memory - one I've been using in this machine - one set is new and was purchased for this board specifically from Crucial. Tried both.
Have 2 PCIE16 video cards - same result with either one.

This one has a blue light that's under the ASUS logo on the underside of the board. It's lit when power is applied to the power supply whether the PS is on or off. That seems normal.
The case fans start up.
I disconnected the hard drives too.
There is no memory installed right now - waiting for beep codes.....
Here my troubleshooting procedure :
with a new motherboard : verify if all mounting standoffs correspond with the holes in the mobo !!
Or test the mobo ouside the case, on a wooden (non conductive) surface
clean the system from dust, then test with the minimum setup - disconnect also all peripherals and network cables :
connect only motherboard + cpu + 1 ram stick, video card, power supply
verify that the 4-pin or 8-pin CPU Aux power plug is connected
on boot, do you have a display?
if NO it is one of the connected, swap ram, Power supply, video card or monitor - leaving only motherboard and cpu
if Yes, add devices till the problem shows
you can also check the motherboard for bad capacitors as shown here : www.badcaps.net
additional tests and things to try :
boot without ram, it should beep; (also, without video card)
try bios default settings,(if possible) or clear the bios by removing AC and bios battery
Check the attached file for ASUS P5B Deluxe beep codes.

I have the same motherboard and did go through a lot of problem with it recently.
My problem was a memory stick that died and made my system unstable.
Way to fix it is to run the memory test by pressing f8 untill you isolate the stick that is dead and remove a pair.
However in your case if I understand correctly the Bios dont even boot up.
Its usually because a component failure or miss connected one.
I would first check if the green light led on the mobo is on, its next to the sata connectors. If its not. Its either your power supply, power connection or your motherboard itself.
If works with another power supply. Its probably your power supply that fried. No fan running or anything would be a huge hint.
