congrats on that.Ae Allah the problem has been fixed as per my knowledge. Running games easily now without any problems. Before fixing, it would give black screen on boot and computer would not respond. Now it is running games like Trine 2 etc (dont have any games since windows8.1 was newly installed ).

Before installing drivers, games through the gpu were running at 2 or 3 fps. now 60 fps as usual.
you have to be careful while u use it now though.
monitor the temps at every moment when u game. keep it at a stable and maintained position.
secondly i just got to know by your PC specs that u have a CM extreme series PSU.
well it could have been the culprit. change it with a corsair or any other quality brand/model when ever u can.
the problem seem to have been electrical
moreover, if u don't use a stabilizer with your PC. then it is highly recommended to u to use a good servo motor stabilizer like stabimatic to get to a safe edge.
