I know connecting those wires to the motherboard is hard but its important you have them going in the right direction. Consult your motherboard manual and be sure you have EVERYTHING plugged in correctly. Be sure your RAM is seated in the correct slots, that they are seated firmly, and that they are compatible with your motherboard. Be sure your processor is seated correctly too. If this is your first time building a computer keep in mind that static electricity is a big killer of computer components. Be sure to ground yourself out before installing anything. If everything is plugged in correctly, and there are no beep codes you may wish to contact your motherboard manufacturer to additional support.
