Inspiron N5010 Crash

I brought my n5010 laptop less than year ago. I brought it as second hand. my laptop was working fine and there was no error.
But one day It gives me an error for graphics drivers (windows 8) and it crashes after then it was its routine to crash on every time.
The I changed my OS to windows 7 and laptop was OK again 
but now its doing the same
I ran the diagnosis many times but it won't give me any error.

I attached a picture of how it behave when it crash and restarted.
