Ok so I have everything set up and the wires all where they are supposed to be to the best of my knowledge from following the install guides and help from a brother. Now when I start it up, the fans will turn for about a half second then power off. I tried unplugging drive cables and the 24 pin from the motherboard and taking out the battery for 30 seconds and reconnecting it all. Still nothing. Anyone have any ideas?
