Today I finally started to build my new system. I followed every step precisely but it just won't turn on. The 8 pin cpu cable is connected, as well as the 24 pin. I know the power supply works. The only thing I can't figure out is that all of the tutorials show these 2 pin connecters such as power switch and LEDs being plugged in to a 7 pin spot on the motherboard. My power supply did not come with these, nor did the motherboard. Would these come with the case, and are they even fundamental to starting the pc? (I'm trying to test it breadboard right now - the case hasn't come in yet)
