Message say unsupported adapter installed, then it shuts down

When turning the pc on, three long loud tones are made followed by 3 short tones. Afterwards the hp logo comes up followed my the message: unsupported adapter installed. Computer will shut down in a few seconds. At the bottom it says press esc key to exit but it will not work.

Hi

 

Is there an adapter, like a WiFi board that could be the cause?

 

Does  ESC and then F2 run a diagnostic?

Hi

Could you please expand on the

MAKE, MODEL, OS and SKU?


My best guess

 

Hardware

The embedded controller has timed out waiting for BIOS to return from graphics initialization.

Pressing escape and f2 didn't stop it from shutting down after the 3 long beeps and 4 short beeps. I do have a wireless mouse and keyboard
