从小型转储诊断 DPC 看门狗违规

自从系统管理员将我的电脑升级到 Windows 10 以来，它每天都会崩溃。我并不总是会看到蓝屏，但当我看到蓝屏时，我看到的只是“DPC 看门狗违规”，这似乎太笼统了，没有任何意义。

由于公司政策原因，我无法采用直接的解决方案（降级到 Windows 7 或购买一台新电脑）。不过，我可能有机会更换一个小部件（例如 RAM 模块）。

我有时会*.dmp在 处收到一个文件C:\Windows\Minidump。是否可以处理该文件并找出崩溃后可能存在故障的驱动程序或组件？

我已经安装了Windows 调试工具但我完全缺乏使用它们所需的技能。

使用 Windbg.exe 分析 dmp，显示nVIDIA存储驱动程序导致崩溃：

DPC_WATCHDOG_VIOLATION (133)
The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL
or above.
Arguments:
Arg1: 0000000000000000, A single DPC or ISR exceeded its time allotment. The offending
    component can usually be identified with a stack trace.
Arg2: 0000000000000501, The DPC time count (in ticks).
Arg3: 0000000000000500, The DPC time allotment (in ticks).
Arg4: 0000000000000000

因此 Firefox 触发了磁盘 IO，而 nVIDIA 驱动程序花了很长时间来处理磷酸二酯酶并触发 Windows 崩溃以防止 Windows 挂起。

寻找驱动程序更新并检查是否可以解决问题。
