Cause

Solution

 

 

 

Power failure (power supply is overloaded).

1.

If equipped with a voltage selector, check that the

 

 

voltage selector, located on the rear of the power supply

 

 

(some models), is set to the appropriate voltage. Proper

 

 

voltage setting depends on your region.

 

2.

Check if a device is causing the problem by removing

 

 

ALL attached devices (such as hard drives or optical

 

 

drives and expansion cards). Power on the system. If the

 

 

system enters POST, then power off and replace one

 

 

device at a time and repeat this procedure until failure

 

 

occurs. Replace the device that is causing the failure.

 

 

Continue adding devices one at a time to ensure all

 

 

devices are functioning properly.

 

4.

Replace the power supply.

 

5.

Replace the system board.
