Welcome back to the forum.
I am not a HP employee.
Are you getting power from the wall outlet?
You should see a solid green power supply LED at the rear of the case. No PSU LED suggests trying a different outlet or check the circuit. The power supply may have failed if you have utility power.
Any LEDs on the motherboard or HDD/optical drive sounds when you start the PC? Any top or front case LED activity?
Only use a monitor when starting the PC since you have no USB function for the mouse and keyboard.
It could be the power supply, a short caused by a component connected to the MB or a bad peripheral device.
It could be the MB or (very unusual) the CPU.

No video and no mouse/keyboard function but you see LED activity and hear startup sounds when you turn on your PC. The power supply LED at the back of the case is solid green.
I think you have a power supply or motherboard problem if you are only connecting the above devices to the PC, the connections are secure, and the devices work correctly.
I can only guess without having physical access to your PC. It is tough to diagnose a hardware problem in a forum.

You would have to replace the MB if you believe it has failed.
It could also be a component connected to the MB. You have to troubleshoot all components before you conclude the MB is the cause.
It could also be the PSU.
Did you ever use a car to find the interior lights and radio work but the car will not start?
