Only had this in Mor Dhona when there's a lot of effects, lights or explosions on the screen at once. Basicly crashes it and resets it, giving you a second of a black screen.

But then again, i seem to have had that on most games with a lot of particle effects, so i'm willing to bet it's just my videocard :/ Which incidentally is the same as yours.

Have you tried diffirent drivers or updating your old ones? Ever since i went to 337.50 it has been giving me the least problems. But even i am going to see if 337.88 gives me even fewer problems.

Sadly, i think the main point is that our videocards could use an upgrade sooner or later. It was a perfect (and not too expensive) card with high specs, but that's been a good three-four years or so by now :/
