ZOMFG! 12v was connected to the motherboard, but not to the PSU!
It turned on and made a single beep! At first there was a RAM LED on, and so I took one stick out and there are no more error LEDs! It is on right now, spinning like it should! I hope eventually I can make the second memory stick work once I get into BIOS!
Thing is... all I have is HDMI for my HDTV and whether I use my GTX 680 or motherboard HDMI slot - my HDTV says No Signal!
