I know I am probably just missing something stupid here but I can't figure out what. I just bought a new motherboard because my last one was giving me a lot of trouble and I just installed it. When I plug it in the LED for the motherboard lights up but when I push the power button the computer does not start up. I do get a slight response initially when I push the power button, the fans turn ever so slightly, but the computer does not initialize. What am I missing here?? Please help soon.. I've been without a computer for a month dealing with all these problems and I am going crazy!
