Problem with video card !!!

Good evening dear friends,have a week graphics card does not work properly in games.
So everything is fine.Take for example the game War Thunder.When you enter the game, everything hangs and does not issue an error.Or Sniper Elite 4 was like 4 minutes, and voila hung !!! Does not issue an error , absolutely nothing more !!!

I've updated Drivers,rolled back to old versions.When zavisa Iron does not overheat.I don't understand what it is like to understand that a week ago everything worked perfectly and right now, all the manure of some kind.
My card is MSI GTX 950 Gerfore.
P. S Visual Stuidio and Dirtex is !!! And Yes the card in MSi Afterburner already tried to disperse a result of no one and the difference too !!!
