Okay, so I recently bought an ASUS G75 Laptop (RoG one):
Video Card : 3gb Nvidia Geoforce GTX 670M Processor : i7 2.30 GhZ OS : Windows 7 Home Premium Service Pack 1 Ram : 16 GB System type 64-Bit
Now when I play a game, may it be Diablo 3 or Minecraft (I haven't tried any other game yet.) the screen flickers of a bit and then it lags, not lag because of internet, but, it lags, the screen flickers, but no blue screen and then it lags, i've looked at an article but it only tells about Radeon. I tired installing RivaTuner or tunnel or whatnot, but it doesn't seem to be showing anysign of help, I would really appreciate it if you guys would. I don't know if I should download Service Pack 3 or a new Nvidia driver. Thanks.

when mentioning service pack 3 did you mention service packs for windows? AFAIK the latest service pack for windows 7 is SP1. btw try reinstalling your driver and see if it fix the problem. you can also try the latest beta driver if you want to.
