I can suggest one thing to you....
uninstall all the video drivers from the control panel
run an app called "Driver cleaner pro" which finds and deletes ALL old files that remain in the hard drive AFTER the driver has been "uninstalled" and then make a clean install with a newer driver downloaded from the NVIDIA website directly. It solved all my weird error message problems and video quirks
