( Why power surge protector ? There are times when the computer that tries to get
power from the Voltage Regulator -- is actually not getting enough power due to multiple hardware plugged into the regulator.
If the ampere requirement is insufficient for the total requirements of all the connected appliances, it is possilbe to have
insufficient remaining power for the computer to draw. Check your pc required Wattage as well as the wattage requirement of
the other appliances. Is the total requirement capable of being provided by the Voltage Regulator ? )
