There are three different models with the HP Compaq Pro 6300

Here is the manual that covers the MicroTower and the Small Form Factor

http://h10032.www1.hp.com/ctg/Manual/c04034127.pdf

On page 192 are the beep codes and LED codes.

The 4 beeps is - Power failure (power supply is overloaded).

To the right column is the recommended solution.

Sorry @Prométhée   took me too long to answer
