HP Pavilion All-in-One - I get 3 long beeps & 4 short one

pavilion all in one
Microsoft Windows 10 (64-bit)

On power up of my HP Pavilion All-in-One - I get 3 long beeps & 4 short one. This sequence repeats 5 times and pc boots up normal.

 

The troubleshooting steps are very confusing. can someone translate into layman's terms? and is this something i can do at home or do i have to get repaired? hah, too techy!

 

Hardware
3.4
The system board displays a power failure (crowbar).*
Indicates potential power system failure.
  1. Reduce to minimum config (CPU, System board, PSU, 1 DIMM of memory) and isolate failed component.
  2. Reduce further if issue persists.
  3. Test known good PSU.
  4. Replace affected component.
  5. If unable to confirm source, replace CPU, System Board, PSU.

Hi

Hardware

3.4

The Main-Board displays a power failure (crowbar).*

 

Indicates potential power system failure.

1 Reduce to minimum config (CPU, Main-Board, PSU,

Single memory DIMM) and isolate failed component.

2 Reduce further if issue persists.

3 Test known good PSU.

4 Replace affected component.

5 If unable to confirm source, replace CPU, Main-Board, PSU.

 

So remove / reduce the things connected, even down to having only 1 stick of ram.

I realise an AIO makes this difficult.

Thanks you for your advice... do you mean to open up the computer? (Yes all-in-one). What is a PSU?  I think it might be over my head...if so, I will take it in for testing/repair...

Hi

The PSU power supply unit, is it external?

Without a model number and/or SKU: targeted help cannot be given.

 

There is very little that can be done to an all-in-one, with the clue being in the name.
