One of my friend is saying,it is due to hardware problem
i can't understand one thing,is it really due to my hardware fault or game fault
Btw I play original games.
i dont prefer pirated editions
please suggest me something what i have to do!!!

I would try updating your AMD graphics driver to the newest you can find (check the betas if possible). It could be a hardware problem but then it would likely happen in other games, not just Saints Row.
