a 10.2-cm (4-inch) clearance at
the back of the system unit and
above the monitor to permit the
required airflow.
2. Make sure the fans are
connected and working
properly (some fans only
operate when needed).
3. Make sure the processor
heatsink is installed properly.
Power LED flashes Red

Processor is not seated
properly or not
installed. (This is not an
indicator of a bad
processor)
1. Check to see that the processor
is present.
2. Reseat the processor.
