Thanks for reply .. It's not with me now because I gave it back again to the service center
But I know they will not fix it , They even didn't accept to receive it on second time saying no problem was found .. I did open one movie for them for 5 minutes and it started freezing again
I feel it's hardware issue .. It had this problem since I received it with windows 8 , I upgraded to win 10 & the same probelm remained
