It's my first time, I think I've got the parts all in there good, well thought. I plugged in the computer and turned it on, the Power supply is buzzing at me, there are 3 fans on the inside of the case, none of them start up, the fan on the CPU doesn't start up nor do the 2 fans on the power supply...what could be wrong? would something hooked up wrong on the motherboard cause this possibly? I know I have the 2 main psu to mobo cords connected properly but past that I might have screwed something up.
