When turning on my PC if I do not turn on my monitor FIRST the fans will spins and the lights will turn on but no power will be sent to the keyboard, mouse and no display will be output. I have tried waiting and seeing if I could log in to windows blindly but it does not even reach that point. (Plus no power to any peripherals) It simply does not do anything. This error is repeatable and can be recreated. I have never had this happen before, this is a new monitor as well connecting to my new computer. It never did this with my old display so I'm not sure what is happening.
Update: The problem now persists regardless of order. So regardless of whether the monitor or PC is on first, it will not boot. I have to press the reset switch at least once, sometimes twice for it to boot.
