2 things I found you need , If Novabench will not load is check your version of .NET, look on this page, https://novabench.com/docs/getting-started Also another thing I found is after I updated my version of .NET is you have to have a wide screen format Monitor I was going nuts trying to figure out why it wouldn't work before , I 'm not a gamer, i just like to have my PC's running at their best. But I had had a Dell 17 " (Dell model E173FPf) non wide screen monitor and Novabench just would not run I would click on it and NOTHING would happen.
I had this computer siting on the floor with the monitor sitting on top of the tower and didn't care if I had a good monitor at the time just to check it out.
After thinking about it I hooked up the wide screen monitor a ( Dell model IN1910N) and then NovaBench worked just fine. I guess it needs the higher resolution to work. But then again there is no minimum resolution requirement mentioned in the documentation for the program to run correctly.
I hope this helps a lot of you guys with this problem.
