He means the power supply.
If the light is blinking near where you plug in the power cord, Then you need to replace your power supply.

Edit:
Actually, This could mean multiple things.
It could mean that one of the positive wires is grounding out to the case itself somewhere and is causing a problem. or a wire could be crossed (More likely for those two options if you move your comp around alot)

But if your comp is not moved around alot or moved recently, Then it is the power supply.
