Alienware 18 laptop - green flickering pixels on screen

Good Morning all,

My Alienware 18 has two duel Nvidia 780Ms, just yesterday my screen started flickering green pixels all over, On the intergrated gfx card this does not happen, nore does it on an HDMI out using the 780Ms, I tried upgrading and downgrading drivers to no avail, a pixel freeing program does not help either.

The internet seems to think my GPU is dieing, the Alien Autopsy  program does not agree (even after running EVERY test).

I worry that this has happened now seems as my warranty runs out in a week!! timing is not on my side.

any help would be appreciated.

Thanks,

Chris
