Purchased a G75VW-NS71 back in October 2012. Has the 670M, and I have been running all original drivers, bios, and setup that it was shipped with. I've never had a single problem in any of the games I play. Windows 7, 12gb ram, all stock no overclocks.

A few nights ago playing Bastion the screen froze, background music still played, and the screen slowly began to turn white. I was able to alt-tab to windows and the problem went away. Quick look at the temp ~60C no big deal. Go back into the game and play fine for about 30 mins. At this point I restart the computer and load up Bastion again, and after about 10 mins the game freezes and the screen begins to turn white again. This time however the computer will not respond so I have to do a hard reset. Once back up I try a different game, Tropico 4, which runs around ~70C on the gpu. No more than 5 mins into the game the same freeze and move to white happens. Hard reset again, and I load up furmark to do a sanity check. As soon as the gpu hit 63C the screen froze and began to turn white.

Sent a message into tech support, they said update the bios. So i'll try that and see what happens, but it definitely sounds to me like the gpu is either not getting good contact with the heat sink or its simply about to die. Anyone have any ideas?

Will post full system specs tonight and anything else that anyone thinks might help.
