G780 Nvidia 630m Refuses to use dedicated graphics card

Okay so I have the G780 Windows 7 64-bit i7 core 2.9 gHz. 6GB RAM, 750GB HDD, Intel Graphics 4000, and the NVidia GT 630M dedicated 2GB card.


So for the past two years I have had this computer and have about 20 games, that at one time worked perfectly fine, until one day I decided to launch a game (Dishonored) and it crashed. So I decided to play another game, Sleeping Dogs, and it crashed as well. Launched Borderlands 2, what do you know? It crashed too.


So I downloaded TechPowerUp's GPU-Z to see if the GPU was running, overheating etc. Found out as I was running Borderlands 2, it was using the integrated 4000 HD graphics instead of my dedicated.


Now I have been having several problems with this. I have updated Nvidia drivers to version (1/15/14), running Graphics Bios Version 70.08.a8.00.43 and have updated the Nvidia Control Panel to the latest version. This program barely works and even though I have personally gone in and added every game's .exe file to the "Use High-Powered Graphics" setting, it still refuses to run on dedicated and runs on integrated as seen by GPU-Z.


Any help here?
