The first time I booted up a newly built computer it was just fine, but then for some reason it shut off. Now when I try to turn on the computer it turns on but then in a split second turns right back off. I know it has nothing to do with the power supply, because I tried using the power supply from my old computer and had the same results. PLEASE HELP!!!!
