NOTE: I used to have this GPU installed a few months ago and everything worked perfectly and my games were running at smooth FPS. However I uninstalled the GPU and removed it from the PC as I was planning to upgrade, but never got round to it.
I recently restored my PC to factory settings and installed a fresh windows 10 and decided to reinstall the 960 again. After that I used DDU to uninstall my graphic drivers (not sure if this was necessary after a system restore) , and then reinstalled my gtx 960 along with the nvidia software and latest graphic drivers.
However, when playing Minecraft I have extremely poor fps averaging 5-10fps even using Optifine and nvidia optimised settings on Minecraft. The display quality is also very poor (the black shadows and white/coloured dots etc.) as you can see in these pictures:
