Need Help. This is my first comp build. I just built my computer from start to finish and when I turn the power on the CPU Fan does not spin and there is no video signal to the monitor. Im thinking I might not have the power supply hooked up correctly. I have a 20 pin connector, but I also see a additional 8 pin connector on the motherboard. On my power supply I have an additional 6 pin yellow/black, a four pin yellow/black and another 4 pin that's multi colored. Can anyone advise which connector is supposed to be used in the eight pin or is this not a compatible power supply. Thanks sorry about newbieness but its my first build and im frustrated. Thanks in advance.
