Hi:

 

See this link for how to troubleshoot the beep codes your PC is emitting.

 

HP Desktop PCs - Computer beeps or a light blinks during startup | HP® Customer Support

 

The red light blinks three times, and then four, short white light blinks (3 long red, 4 short white)

This condition indicates a potential power system failure.

  1. Reduce to minimum configuration (CPU, System board, PSU, 1 DIMM of memory), and then isolate the failed component.

  2. Reduce further if issue persists.

  3. Test your system with a known good PSU.
