The system board displays a power failure (crowbar).*
Indicates potential power system failure.
  1. Reduce to minimum config (CPU, System board, PSU, 1 DIMM of memory) and isolate failed component.
  2. Reduce further if issue persists.
  3. Test known good PSU.
  4. Replace affected component.
  5. If unable to confirm source, replace CPU, System Board, PSU.

if you are under warranty, contact your dealer, or hp directly
It is difficult to identify the pane, it may be the power supply.
But it could well be the motherboard or something else
Otherwise, go to a professional, he may simply be able to test another power supply.
