Do you have any problem with your gtx 570 / gtx 580 with drivers 263.09?
What happens to me is that the driver stops and then recovers. What is interesting is that it only happens when i have Asus Suite II running. No problems playing games or anything like it. Just with the asus suite BOOM

Asus suite works fine, but sometimes when i'm browsing on the web it simply stops.
