I have a problem with the dedicated 880m card that was purchased with this system.

Some time ago I started to have random freezes and crashes of the game  but now since 2 days back I cant start a game that uses Nvidia card without a crash/blue screen in windows.

I have reinstalled the system few times, installed various versions of drivers and keep going wrong.

Is there any particular think that could be done? (re-pasted and re-sitted the cooling on the card) still no joy.
