So I have been dealing with this problem for a while now and I've just had it. I run a GTX 980 and the drivers just always seem to crash while playing some intense graphic games. I picked up Metro Last Light Redux on the Steam Christmas sale and I can't play it for more than 30 minutes because my driver crashes. Naturally the first thing I did was role back the drivers, that didn't work, uninstalled and reinstalled them, didn't work, then I uninstalled them and reinstalled them using the driver disc those didn't work and updated them from the disc drivers and still the same problem.
Every Nvidia driver I seem to use it always crashes and it doesn't do this for games like Battlefield 4 and Crysis 3. So I tried to reinstall Metro and still the same problem. Any ideas on what could be happening? The games run smooth 60+ fps on highest setting and it just crashes. No rhyme or reason, on the lowest settings to the highest.
