I've been clearing out my Event Viewer using a batch file I found a good 18 months ago. Gives you a clean slate to look at. I can't remember where I found the batch file but this one is (nearly) the same.
They don't delete the actual .event files, just clear your event viewer.
I feel that this is not what you are really looking for though. You are looking for how to fix it so you no longer get the error messages
