Welcome to the forum.

I am not a HP employee.


You have an unspecified hardware problem if the PC is power cycling and only fans spin.


Could be the power supply or the motherboard.


Could be a short in a component or a failed component/device connected to the motherboard.


Best to have HP Support (Link) or a local tech take a look.
