There is still some sort of Avast installation on your PC. This is from a dump created at 00:05 on the 13th of March, if you uninstalled Avast after that time ignore the code below. If you uninstalled Avast before that time then download the Avast uninstaller linked below the code and run it to remove all traces of Avast.

Your nVidia drivers have been flagged again. Download this earlier version from here and follow NVIDIA Drivers - Avoid Problems for the cleanest possible install. This is the most stable nVidia we know of so please test the machine with this driver installed. If the problem persists we may have to take a look at the card itself.
