Hey Locus,

You could give a "perform a clean install" tickbox a shot, it's an option during nvidia driver installation.

Also, you could eventually try this:

before trying out a new version.

If you are experiencing weird behavior in other apps, it could be heat or psu power cap/quality related.

Good luck!
