System Cooling Fans Do Not Rotate

No Characters Appear On Screen

Note: The system has two cooling fans: one is mounted on the
chassis panel behind the front panel LEDs and the other is an
integral part of the power supply. There are no serviceable
components inside the power supply. If the power supply is
opened, the manufacturer's warranty is voided.
Check the following:
Is AC power available at the wall outlet?
Is the system power cord properly connected to the system and
the AC wall outlet?
Is the front panel power on indicator lit?
Is the power connector for the front cooling fan properly
connected to the system board?
Is the cable from the front panel board connected to the system
board?
If the switches and connections are correct and the power outlet is
functioning, the power supply has probably failed. Contact your
service representative for assistance.
Check the following:
Is the video display plugged in and turned on?
Are the brightness and contrast controls properly adjusted?
Are the video display switch settings correct?
Is the video display signal cable properly installed?
Is the onboard video controller enabled?
