I recently had to move to my upper floor of the house, so i moved my computer along the way. When i plugged everything in the case and tried to turn it on, the power led flashed as long as i held the button but couldnt turn on in the end. I recall that it displayed the same flashing signs a few days ago when the power went out, but just for a brief moment before it turned on. Does anyone know what im dealing with? If so, please tell me what to do.
