Please uninstall everything of Nvidia using Display Driver Uninstaller and install new drivers from Nvidia. Be sure the clean install box is checked and only install the Graphics driver and the PhysX driver, you can use this tutorial to do so NVIDIA Drivers - Avoid Problems - Windows 7 Help Forums

Please don't forget to make screenshots of the results and uploading them :)

I ask for screenshots because of a few reasons, in the past it occured that some lied about those results as they didn't want to troubleshoot the HDD although it was certainly the cause. It only happened once fortunately, but it is 1 of the reasons why I would like to see screenshots. Another is to check if the error code or result is as the user describes, it occurs frequently that the user mentions a different result/error code than the reality shows and we need to adjust our suggestions so they fit with the result/error code.

Could you please install a few different drivers from Nvidia to see if that make any differences.
Please uninstall and install the drivers per the instructions of my previous post in this thread :)

Please fill in your system specs

Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely including PSU, cooling & other used stuff. Please note that the PSU, cooling & other used stuff are NOT mentioned in the tool.

How to fill in your system specs:

I do understand it too, but that only makes things more difficult for troubleshooting what only takes more unnecessary time.

With different drivers from Nvidia I indeed mean older drivers, newer drivers aren't always the solution though it is standard advised as it helps many times. I would suggest to try a few drivers that are known to be stable, unfortunately I'm not really aware of any of them, because when I search for such drivers I only find negativity about drivers.

Thank you, I'll look forward into your next reply or next question :)
