alienware m15x bluescreen (stop: 0x00000116, nvlddmkm.sys)

hello, first of all i'm sorry about my bad English to start with

so best way to describe my problem is i am having a blue screen when gaming or watching videos often (stop: 0x00000116 and nvlddmkm.sys)

so i've tried downloading few drivers but im still having the same problem, also having a problem of screen freezing up while gaming and it's really bothering me.

thanks in advance
