Greetings @1N1218002N 

 

Welcome to the HP Forum.

 

Opinions or troubleshooting suggestions in this response are provided independently. I am not employed by: HP, Inc. or the HP Forum.

 

I would think the system has a MB add-in component problem or a MB SMT component problem possibly causing a short to ground or a dead power rail if the PC will not start and the power supply is good to go.

 

You're probably going to need a PC/electronics Tech in this scenario if the MB has issues.

 

You could try running the PC in a minimum config:

 

- Power supply

- one stick of known good RAM

- Known good graphics card or onboard graphics

- CPU

 

Then swap in known good components, one at a time, until the PC will POST. MB failure would be indicated if the PC will not POST using known good components.

 

Regards
