Alienware M18x R2 (Early 2012) sli red flickering screen

Hi, everyone. I'm from Hong Kong(not a native english speaker)so please ignore my poor grammar.

GPU: Nvidia 675m x2

The problem I'm having is whenever i open a game in "FULL SCREEN" mode(Any game) with SLI is on, the screen starts to flickering in red(just like what u will see when you video tape the old non-LCD/LED TV). It's fine when i disable SLI but low fps.

Sometimes, the screen freeze and stay that way, and i have to do a hard re-set (holding the power button). And it saids the 675m driver "C:\Windows\system32\drivers\nivddmkm.sys" crashed and caused a system crash.

I've tried to reinstall both intel and nvidia drivers, full system check up with AlienAutopsy but nothing work. Both GPU temp. were around 60~80 while gaming(with my coolermaster cooling pads under).
