@Ron2198, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Power Cycle the PC

Turn off the PC and unplug it.

Press and hold the power button for 15–20 seconds to discharge residual power.

Plug it back in and try powering on.

Check Display Output

Ensure the monitor is turned on and connected securely (HDMI, VGA, or DisplayPort).

Try a different cable and/or port.

If your system has both onboard and dedicated graphics, switch between them.

Try a different monitor if available.

Listen/Look for POST Beeps or Lights

Systems have diagnostic LEDs or beeps during POST (power-on self-test).

No beeps or lights can indicate motherboard or PSU failure.

I hope this helps.

Please feel free to reply here if you have any questions or if you need further clarification on any of the steps. 

Take care and have a good day.
