I just recently got all the parts for my new gaming computer and I put the whole thing together last night. I went to turn it on and nothing happened. I disconnected everything except for the Mobo(Asus Crosshair V Formula), the CPU+Fan(Amd Phenom II X4 3.4GHz), and the RAM(G.Skill Ripjaw 2 x 4GB). I then tried turning it on again and nothing happened. I made sure all the power connectors that needed to be plugged in were plugged in and nothing happened. I know its not the power supply because I tried the PSU on a different computer and it worked. I'm wondering if there's anything I'm missing or if the motherboard is defective and I need to return it. None of the stuff I ordered was used or open box, it was all new. Thanks.
