Welcome to the forum.

I am not a HP employee.


A AIO PC has almost everything integrated on the MB except for the storage and RAM.


You have a hardware problem with the external power supply or the MB.


A tech would have to diagnose unless you are familiar with this process.


Contact HP Support (Link) or find a local PC tech.
