Question about HP PC Desktops
Sounds like a Power-On Self Test (POST) error.
Usually one long and three short beeps indicate a memory error.
Could anything have happened to dislodge the memory? You could try unpluging, taking out the battery, earthing yourself and then removing the cover on the memory enclosure (usually one screw at the bottom releases the cover). Check that the modules are pressed right home into their clips.
If there is more than one module, try removing one at a time to see if there is one failed one.
If the memory has failed, you are looking at new memory I'm afraid.
