I would first make sure your have the latest updates for your Mac installed.
Click App Store in the Dock then check for any available updates then install them.
Restart your Mac.
As for the Auto Update, I would try installing a new version to see if it it helps.

That version came out on March 14.
As for Chrome, launch Finder in the Dock
Click on Applications
Select Chrome, right click it then click Move to Trash
Restart your Mac, download and reinstall Chrome.
