computer just beeps -3 long and 3short 5 times

[nok1]

The computer is off. I turn it on and it just beeps three long then 3 short beeps. It does this 5 times and then just sits there.

I have unplugged it and pressed the on/off button several times and then tried again with the same results. There is nothing else connected to the computer except the mouse and keyboard. I have tried the process without the mouse and keyboard with the same results

thanks

Greetings,

Welcome to the forum.

I am not a HP employee.

I don't know your specific product number. 

A AIO PC usually has integrated graphics. This means you may have to replace the system board.

A 3:3 beep cadence on HP PCs manufactured in the last three years means the following extracted from this HP Support site (Link😞

Hardware

3.3

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

Indicates potential graphics chip failure. For integrated configuration: For integrated configuration, confirm if graphics is on processor or system board. For integrated where graphics is on the CPU, swap known good processor. For integrated configuration, replace system board and/or processor as appropriate. If the add-in card requires additional power, verify the cord is plugged in. For non-integrated configuration: Reseat card if able. Test known good card if able. Replace affected component.
