Hello, I'm having a problem with my computer that in-games, It reboots after about thirty minutes. Some information, CPU: I7 2600K, M/B: Asus P8P67 Rev, GPU: Gainward GTX 680 4MB, And 750W PSU. I've SSD Of 64Gb for O/S, only 4Gb free. The GPU Temperature after 30 Minutes of benchmark Is eighty degrees And there's no crashes, But, when enabling V-sync(Benchmark), It's crashing at one moment. And the last, I'm using Dell Screen with 2560x1440 Resolution, If it's matter. Thanks, Thomas.
