Dell N5010 Graphic Driver Crashing.

Hi All,

I have dell n5010 laptop, for the last two weeks I am getting blue screen due to display driver crashing. I tried to install fresh windows 7 copy and driver from dell but nothing solved the problem. Now when I am running windows in normal mode(Aero theme) I cannot see anything except line and square block on the screen. I have changed the thermal compound of gpu and cpu also but still that is getting heated.

Note: when I ran the diagnostic mode, everything looks ok except DST Hard Drive Test failed.

Soon I will upload the screen shot of images.

Please help If anyone has observed the same situation earlier.

Thanks.
