笔记本电脑风扇无法打开图形

大约两年前，我购买了三星系列5（不是超级书本NP510r5e）。时不时地，当我执行一些图形要求很高的操作时，笔记本电脑便会关闭。

在使用带有卫星视图的Google地图时，我首先注意到了这个问题，最近在玩游戏时，我又注意到了这个问题。它开始了，大约五秒钟后，一切都关闭了。我不太确定，但是我认为笔记本电脑具有Hybrid Graphics，即一张低功耗的图形卡（Intel，嵌入在CPU中）和一张更强大的图形卡（ATI Radeon）。但是，lspci仅列出英特尔之一：

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

我认为有两个不同的问题。首先，无法识别ATI卡。其次，风扇不会继续运转，CPU嵌入式显卡（我什么也没听到）会过热，并且一切都已关闭。我进行了许多仿真，使我的核心保持繁忙，并且散热从来都不是问题。仅带有图形。

我一直在运行Debian wheezy和jessie，两者都有问题。我直到最近才意识到我拥有第二张图形（ATI），因此使它们工作并不是我的优先考虑；相反，我希望我的计算机首先调节其温度。有什么建议吗？

这是一些输出：

而且，我也很乐意提交一份lshw。
