I just build my first pc and when I turn it on the fans start up the lights turn on and then it shuts off... I've tried unplugging my optical drive and trying with only 1 slot of ram and same thing. I sorta kinda sure that everythings plugged in correctly.. I guess.. i assume it's the motherboard but, I don't want to unbuild it or anything :'( it took me like 7hours to build..
