我在这里发帖是因为我正在使用 Ubuntu，但这可能是硬件问题。自从我购买了带有 AMD Athlon(tm) II X4 635 处理器和带有 ecc ram 的 asus m4a89td pro/usb3 主板的新设备后，我的视频就出现了卡顿。我之前使用的是 ubuntu 11.10，现在是 ubuntu 12.10。查看系统日志时，我发现这种情况会定期发生（我只在视频上注意到，但这种情况总是发生）：

我有：
- 更新的 BIOS；
- 尝试了所有（真正的）BIOS选项；
- 更换了内存；
- 更换了 psu 和 cpu 冷却器；
- 尝试了 3.8.1 内核。
我现在能做什么？
请帮我！
谢谢，马里奥
