New Builder..Almost There Please Help =) Thanks in advance

Hey guys whats up?, Im stuck here on my first build, I havent updated the bios yet and installing a 1090t cpu in a MSI 890FXA-GD70 mobo. (specs below) I put all my components together and turned on my new pc and it turned on but didnt display and video and I couldnt go into bios or install os.

I did some googling and figured out that I didnt connect my 8pin power from my 650w psu to my mobo. So I connected the 8 pin (4+4 pin) and tried again...it turned on everything was working for one second then it turns off and I cant get into bios or see and video from my 5740, the cpu phase light quickly flashes and the ddr phase light lights up fully, and stays on even after the mobo shuts off after that 1 sec of operation. PLEASE HELP ME, I would appreciate it so much you have no idea.

Note: I have my dvd drive & 3g sata hdd in my 6g sata slots on my mobo if it matters.
