Okay so I am making my first PC build ever, I got the CPU, CPU Fan, RAM, Motherboard, DvD Drive, Hard Drive, Wifi Card, and My GPU hooked in. When I flip it on, my fans run and everything works but, my Gfx card isn't spinning, and my USBs are not working to plug in a Keyboard. I am running the Corsair CX 600M, and gigabyte GA-970A-D3P Motherboard. Please help, if you can.
