我遇到了多个 BSOD 问题，最近的一个是；
PAGE_FAULT_IN_NONPAGED_AREA 失败原因：portcls.sys
渲染高强度游戏时会出现问题，但现在 BSOD 只会在空闲时发生。我的设备是定制的；GPU：GTX 970 Strix
CPU：英特尔第二代 i7 2600k（1155 插槽 sandybridge 3.4GHZ）
内存：16Gb razor（2 x 8GB DDR3）
主板：华擎 Z77 Extreme 6
电源：Crosair CX750W
存储：OCZ-VERTTEX4 250GB SSD 和 PNY CS900 120GB SSD
有人告诉我要通过 Windbg 工具分析我的转储文件，因此我进行了尝试，我绝不是说我是这方面的专业人士，但我尝试通过该工具打开文件，如下所示；

我不能 100％ 确定我是否正确执行了该操作，但我确实通过 %SystemRoot%\Minidump 打开了转储的源文件。
提前谢谢了，
