@jediknight36 Replace the power supply. I've had a $5 chinese power supply for my pi2 give me the lightning bolt like 1-2years later. Opening it up, they used very thin wires that just gave out from the thinness and poor solder job. Replaced them with thicker ones and all's good. Zero issues with my official pi power supplies.

Element 14 is one of the main distributors for raspberry pi, it is probably as official as it gets.
