There is one more thing that you can do that might resolve the problem. Some hardware does not actually fully power off when turned off so they store some information from previous sessions, this sometimes causes problems like you are talking about. I recommend powering down then disconnect from the power source and let it sit for 5 min. Then reconnect and power, turn the controller on and see if that solves the problem.
