Nvidia 750ti crashes

Guys the problem I have vidyuhi nvidia (reference) NOT chiska. sidelnik bought DNS (I know moron, it was necessary to collect, well, didn't have time.) guarantee flew, opened the lid (I know, moron, I had to go on a guarantee to give).
FarCry 3 at max speed 40-50 fps is all right. fallout 4: writing failed to identify the model of the video card (does not start even at the minimum salary). GTA 5: steam version (bought,Yes, Yes GTA enough for vidyuhi not) as soon as you start the campaign mode the game crashes a minute passed, the game cuernos at the bottom it says: the driver stopped otect and was restored. help pliz
