HP Envy All-in-one won't boot

HP Recommended
HP Envy 27-p014 (desktop all-in-one)
Microsoft Windows 10 (64-bit)

My HP Envy All-In-One (27-p-014) won't boot up.  Power indicator comes on and I get 3 long and 2 short sound beeps and the power indicator blinks the same way (3 long and 2 short).  The screen stays black.  The beeps cycle 5 times and then goes silent while the screen never lights up.  The computer is about 2 years old.  This happened all of a sudden.

Greetings texmass,


Welcome to the forum.


I am not an HP employee.


The POST error code indicates you have a memory problem.


The following troubleshooting steps are recommended by HP Support:


  1. Reseat memory.
  2. Correct memory configuration (correct DIMM placement and size/type matching).
  3. Test with known good memory.
  4. Replace affected component.

You will have to open the chassis to test each installed memory module in each memory slot to find the possible bad stick of memory.


You will have to replace the failing memory module with the same type memory.
