Monitor, mouse, and keyboard do not work *new build*

  1. I recently built a new PC and the monitor, mouse, and keyboard will not power up. When I boot the PC up all the lights turn on and the fans work. I have replaced the mobo and psu and still the problem remains. I even tried taking out the CMOS battery, reinserting it, making sure everything is seated and tried draining the power. The keyboard lights will flash for a second when I push the power button but after that...nothing.

    Could someone give me their insight as to what may be happening please?
