Hello fellow members..
After scraping the web for literally 2months and trying every possible solution i found, i have came to ask the question..
The internet is full of posts/threads/questions regarding this problem, but believe me no one is having a rare problem like me, so please read, i will be very thankful for solutions.
I bought a Gigabyte HD7750 OC 2months ago. I have played the following games since then
Farcry 3, 4. Crysis 2, 3, Battlefield 3, 4. Tombraider, wwe 2k15 etc, all of these ran smoothly and perfectly..
BUT 2 games(discovered till now) Sleeping dogs and Assassin's Creed(IV) BF are causing serious problem. whenever i play any of them my entire PC hangs/crash randomly(become nonoperational) sometimes after 5 mins of play sometimes after 40mins or so, with a constant buzzing sound, and the screen i get is following
for the 1st month of gaming i got a grey(some times orange) screen with vertical lines, but now i get a black screen.

Now this is what i have done till now.
I had HP elite-8000CMT Q9550 8GB-DDR3 HD-7750 320w-psu
i ran memory test, it cleared. i ran furmark stress test for about 20mins, it cleared(tempo never go above 65), when i ran test on cpu (using IPDT-64) it failed, reason the processor was not genuine intel but a sample build(ofcourse this is not a problem)
so the very next day my PC specs were(and still are)
Mobo:Asus-CM5571 Q9650 8GB-DDR3 HD-7750 500w-psu

How my question differs from the internet? the people having similar problem are having it will all games even those with low requirements. i have mentioned all the games above i played for hours and never got this crash, but why these two games ALWAYS crash my PC?

Really sorry for this long post but i am had done all the effort i can do, and i wanted to make the question clear.
