was excited to build my new system 790i nforce mobo ,inel 9300 with tuniq tower H/s , 2gb reaper ocz,750gb hd for data, 3x 9800 tri sli, 1200watt psu. And to my dismay it refuses to start. mobo has blue led on when pluged in and when i try to start up orange mem. light comes on then stays on and green main power light flickers on then goes out and wont respond untill unplugged. Possibly the motherboard ?
