While playing games such as Dota 2, Left 4 Dead 2, Team Fortress 2, Blacklight, etc... The game will crash randomly. The screen will randomly turn black and I will have to go into task manager to close the game. On certain games it will have told me that my display driver has stopped working. Occasionally my entire computer will also crash.The crash can occur anywhere from 5 minutes of playing to an hour. I have tried re-installing windows, updating/re-installing drivers, directX, however none of this works. I put in a different graphics card (Radeon HD 4670) and experienced no crashing, although I did have to turn down the settings of games because this isn't the best of cards.

Motherboard - Asrock z77 Extreme4
Processor - Intel i5 3570k
GPU - Nvidia GTX 670
RAM - Corsair Vengeance 8GB (2x4GB) DDR3
PSU - Corsair CX600 V2 600 Watt 80

Any help would be much appreciated, not looking forward to discovering I have a faulty graphics card.
