I *think* the mainboard is telling you it has a power failure.

Verify that the AC adapter you're using is the CORRECT wattage for your All-in-One.

Newer HP All-in-One's will give you POST beeps if the AC adapter has a lower wattage than it's expecting.

If you can reply with the exact model you have I'll tell you the wattage PSU you should be using.

Greetings Diva21,

Welcome to the forum.

I am not a HP employee.

 

BIOS eror codes for HP PCs can be reviewed at this site (Link).

 

A 3:4 BIOS error code means you have a hardware problem if your PC was made in 2015 or later.

 

Possible hardware issues:

 

Power supply

CPU

System board

 

Contact HP (Link) if in warranty. Find a good, local, PC tech if you are not in warranty.

 

Regards
