I just build this computer it's my first time building one. I have an MSI 970 motherboard, gtx 750i graphics card, amd 6300 6 core processor and the power supply is a 500w. The problem is that number 1, the instructions for the motherboard are just to complex for my knowledge right now but i have the power supply plugged in and the cpu plugged in. the graphics card is plugged into a cord that came out of the power supply and also into the motherboard where it goes. everything is in and i tried turning it on and the only thing that works is the blue light at the front of the power button. the fan isn't plugged into anything either because the power supply only has 3 connections 2 of them are going into the graphics card and 1 into the hdd. i have a PCI-E cable coming out of the power supply that i don't know where it goes either if anywhere. anyway, it doesn't work on except for the blue light in the front. do i have enough power?
