I just upgraded my computer and tried to start it up but it didn't power on. Some of the functions worked but what I really noticed was that the fans didn't work. When they did work though was when I unplugged the CPU connector. All the fans ran perfectly fine it's just when the CPU connector is plugged in everything goes weird. It is not shorted because I checked for that and the PSU is fine becaus I used it on another machine. Not sure if this is human error or what.
