Keyboard lights up, but no Fans spin

So about a year ago my GPU died, and I just got a new one today but when I plug everything in and hit the power switch for the psu, the keyboard lights up and no fans spin, and at this point I haven't even hit the power button yet. When I do hit the power button nothing happens. Anyone have an Idea what is going on?

I heard there were some bad Displayport cables that had pin#20 connected to power where it shouldn't be and that was allowing power to reach PC components before you hit the power switch.

Another idea is that there is a BIOS setting that allows USB ports to have power even though the PC is off. This feature is used to charge USB devices with the PC off. Check those settings in BIOS.
