Greetings,

Welcome to the forum.

I am not a HP employee.

This symptom is usually caused by faulty hardware.

Possible Causes:

-Power supply or power switch

-Internal components connected to the motherboard (SATA devices, RAM, USB front panel devices, discrete graphics, or other miscellaneous devices) or even a faulty peripheral device connected to the PC

- A bad external port such as a USB port

-The motherboard (MB) or, very unusual, the CPU

Only connect a monitor

Check/reseat internal cabling connections and components.

Then slowly reduce the PC to a minimum configuration by disconnecting internal components one at a time if reseating everything does not work.

Check for a successful POST after removing each component down to the MB.
