I finished watercooling my computer and now I have a problem. When the computer starts up it asks me to select a boot device but I cant get into the setup becasue my keyboard isnt turning on. I tried 2 keyboards then bought another keyboard that goes into a usb slot. None of them are working. I tried two diffrent power supplies. Same thing with both. I tried two diffrent pairs of ram,one stick of each. The lights on the mouse turn on and the mouse goes into a usb slot. Is something dead, dieing, maybe I forgot to do something? I need some help/suggestions. Thanks.
