GeForce 940m texture flickering

Hi all,
when I try to use my GT 940m, textures in video games start to flicker like this -
I tried:
1) Uninstaling and reinstaling drivers many times.
2) Made factory reset.
3) Turned off some features like shadows in video games.
This issue does not apply to my second graphic card Intel HD 520 everything runs fine on it.
Should I say farewell to my GT 940m or is there still a way to save it?
