If it won't go past the splash screen, and you have replaced the CPU, I agree that it is probably the motherboard.
One other test you can do is, remove the memory chips, and any cards that are plugged it, and see if it beeps on start up.
If it does, count the beeps. If it doesn't it is the motherboard.
If you get beeps, plug the memory back in, and try again. Listen for beeps. Let us know what you find.
And I don't know if Compaq's do this (Dells do) when you turn it on, do the fans spin up normally? Or does it sound like a small jet? Speaking of which, do you see the fans spin up at all?
SOURCE: Put in new power supply, computer will not boot
Try resetting the BIOS, depending on the motherboard, there will either be a button, switch or small jumpers that will short two pins and reset the cmos on the board. Just make sure to take out all the extra peripherals before powering back up. If you have jumpers, look for the one marked CMOS, not the one marked password. Move the jumper plug over one pin and power the system up. Wait approx. one minute and power back down, remove the power plug from the back and press the power button on the front to bleed off the power. Move the jumper back to its original place, plug the power cord back in and try booting the system back up. If it boots you will need to restart and get back into the BIOS and reset the time and date.

Originally the computer just quit, I thought because of its age it was a bad power supply. Replaced the ps and still nothing. So I swapped the power switch off my Shuttle onto my wifes and hers (broke one) still didnt boot. It worked fine on mine. So I know the power supply , switch and cable is not the problem.
I do have power to the mainboard cuzz it has a green light
Doubled checked all connections, power supplies are the same, did find that the new ps has 1 less pin than the old one however after tracing the wire in the same pin position on my machine and testing voltage (which was 0) it appears to be a deleted connection. Other noticeable issue is when plugging in the 110v all the light come on for about 3 sec. then shut off
