Your error logs paint a real mess of a machine here.
Even with all those software errors though I see nothing indicating a software based reason you should be having trouble with your display.
There are only two steps I can really suggest without concern for worsening your problems.
The first is to reinstall the latest version of your video driver which can be obtained from nvidia. Drivers - Download NVIDIA Drivers
The second is to check your windows files, as the number of software related errors in your log and the frequency at which they are occurring is difficult to explain.
Instructions on how to run a secure file check can be found here: SFC /SCANNOW Command - System File Checker
Even that much is pretty much guess work without memory dumps or direct access to the machine though.
There is a very real possibility you got a lemon too. That kind of image corruption is common with damaged or overheating video device.
