Front USB is not connected.
The ambient temperature could
exceed operating limits
(maximum=95F), or there are
obstructions to airflow, including dust
buildup.
Hard drive is about to fail. (Some hard
drives have a firmware patch that fixes
erroneous error messages.)
The drive is not installed correctly or
has failed.
Recommended action
1. Run the Computer Setup (F10) utiltiy.
2. Verify and replace cables.
3. Clear CMOS.

2. Disconnect power and open the access panel.
3. Verify that cables are not blocking processor
heatsink fans or front fan (if installed).
4. Verify that there is not excessive dust on major
components.
5. If airflow is acceptable and there is not excessive
dust, the thermal sensing circuitry has failed on the
processors or on the system board. You must
replace the processors and/or the system board.
1. Determine if hard drive is giving correct error
message.
