I believe the server is never reaching bios, but it was before, which is why im confused.

Hi @DavidIkeda ,

Symptoms indicate early hardware failure triggering thermal/fan protection mode. Common causes: PSU, RAM, CPU, board issues, or loose connections.

Please follow the quick diagnostic steps:

1. External Checks:
   Test power outlet/cord, monitor, VGA cable.
   Unplug 5-10 min, power cycle. Note auto-power-on (possible short).
2. Internal Inspection:
   Open case, clean dust, reseat all cables (power, data, front panel).
   Check fans spinning; ensure panel closed.
   Inspect for damage (bulging caps, corrosion).
3. LEDs/Beeps:
   Front LEDs: Power (green), Health (red/amber = fault).
   Board LEDs: Near CPU/RAM/fans indicate failures.
   Listen for beeps: None = early fail; patterns = RAM/CPU/PSU issues.
4. Minimal Config Test:
   Remove drives, cards, extra RAM (keep 1 ECC DIMM in slot 1, CPU, PSU).
   Power on. If video appears, add components one-by-one to isolate fault.
   No video? Test/swap PSU, RAM, CPU. Suspect board if all fail.
5. If BIOS Reached:
   Check RBSU (F9), IML (F10), temps/fan status.
   Run Insight Diagnostics from SmartStart CD.

These could be the probable causes:

• PSU: Replace (350W/460W HP unit).
• RAM: Test single module; ensure ECC DDR3.
• CPU/PPM: Reseat, check pins/thermal paste.
• Board: Corrosion or failure
