Pavilion elite power supply light on, won't power up

HP Recommended
Pavilion Elite e9107c
Microsoft Windows 10 (64-bit)
I shut down my Pavilion Elite for 1 week while away and now it will not turn on. The power supply light is on, I replaced the CMOS battery and the power switch is ok.

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

I have been through the tutorial without finding a solution. When the power button is pressed, the power supply light does not go out or flicker. No fans come on at all, including the power supply. Thanks for your help.

I would go back to the tutorial, and unplug the 20/24 pin motherboard and the 4 pin CPU motherboard plugs. The I would do the  "Testing the power supply separately from the system" with the suggested paper clip.  I suspect the PSU took a hit recently when you were away.  This is possible if the power was still applied to the PSU.

I did that and the power supply fan comes on. Looks like the power supply is ok.

The next step is to re-seat the memory (RAM) modules.

I removed all 4 RAM modules and reseated them. Still no change.

Do you have access to a spare power (PSU) supply? 

It's perplexing that the PSU fan will spin when it's jumpered (as a test option), but the CPU and rear case fans show no movement when the PSU connections are applied.

I did not have a spare PSU do I took the PC in for repair. The motherboard has a blown capacitor and they were unable to replace it, so I bought a new desktop today. Thanks for your help.
