There have been reports about this before, even MSI Center causing unnecessary CPU utilization. If you don't really use MSI Center for anything, I'd recommend uninstalling it. Also make sure your power plan is on "Balanced", MSI Center likes to change that sometimes. If you need MSI Center for something (RGB control is the only thing it would be good for, because for almost anything else, there's better other tools), then I would probably uninstall it and install the latest version of it again.
