I am trying to build a desktop for myself. I have all the components I need and have tried to hook them all up. However, only the LEDs for the power button and the battery icon light up and show they are working. Nothing else will turn on. I tried it yesterday and my fan booted up and then I turned them off. Now they wont turn on at all. The PSU fan wont even spin on boot. I have an EVGA 650W non-modular. Any help would be appreciated. Thanks!
