Arduino does not run code wen turned on.

Recently I have been playing around with my Arduino Leonardo++ and it does not function the same way anymore. When I power on the Arduino all lights light up but the TX light Stays on constantly. It does not seem to run any programs other than blink. Until I press the reset button where it springs to life and run any program flawlessly I would prefer not to do this because we plan on using it for my robotics team soon and this will not work.

Please Help, Collin
