BSOD Non stop...

Hello recently my computer crash  everytime (and randomly) when  i  use it.
i use a software called "WhoCrashed"  to know  about the problem.
- It seem that the problem is from a file called  nvkflt.sys.
So i Tried , to restore a previous version of my system,  to reinstall my graphic card drivers,  to update the Bios,  but nothing change..



I don't know what to do now, and i hope  someone can help me.

Thanks.

I'm using  Alienware M17xR3 windows 7
Gtx580M 16 gb RAM i7-2860QM
