K8N NEO4 new old power supply died new power supply installed will not boot

Question

This is an old build. The K8N NEO4 powers up and is followed by a long beep. The lights on the back of the USB card (4 lights( indicate 3 greens and one red in the upper right corner. According to the instruction manual, this means that Initializing Floppy Drive Controller
This will initialize Floppy Drive and controller. This makes no sense.
I flashed the CMOS both using the red button and removing the motherboard battery to confirm the power supply was bad. In hindsight, I wish I had not.
I switched from a 500W power suppply that died to a 430W thermaltake power supply. I've disconnected a hard drive and a burner to see if power was an issue, it was not the cause.
I'm pulling my hair out here, please help!

Answer 1

"Is it possible the power supply took the CPU with it when it died?"
 Yes it's possible that it did that. It's also possible that other components were killed also, that's why changing and trying different parts are required until you find everything that may have been damaged. We can only suggest what might be bad and you or someone else will need to do the actual work, there is no getting around that. We can give the serious advice, you need to do the serious labor.
"...don't want to take the Tuniq tower 120 off if another processor will not work"
 Anybody that repairs PC's would need to swap parts to be 100% sure of what's wrong.
Pin #20 is where -5V would be if newer PSU's still had -5V. The only the reason you would need the -5V is if you had an older K8N MB that had Creative sound on it instead of Realtek.
