@swrluke , welcome to the Community.

Here is a guide that will tell you what the beep codes mean: https://support.hp.com/ee-en/document/bph07107

Scroll down to the section "Hardware 3.4" - The system board displays a power failure (crowbar)*.

It appears the you have a power supply unit (PSU) problem.  You should have it tested.  Also, test your memory, as stated.
