Its not an error - its a warning notice. Sometimes polling the EC sensor can slow things down or cause erratic operation on some motherboards. So Martin (author of HWINFO) added this pop-up that gives the user the option to turn off EC sensor monitoring. I have never had any trouble monitoring my Asus EC sensors but some others have. I suggest clicking on Continue. If you don't encounter any problems, leave it be. If you do, you can tell HWINFO not to poll the EC sensor. If you want to disable it, click "Do not monitor this sensor."
