當系統崩潰在藍屏瞬間，系統會形成一個擴展名為dmp的存儲器轉儲文件，默認存儲位置為C：\WINDOWS\Minidmp。

A．右擊“我的電腦”選擇“屬性”，在“系統屬性”對話框中選擇“高級”

B.在“啟動和故障恢復”中選擇“設置”，具體設置如下圖所示

什么是windebug

windebug是微軟發布的一款相當優秀的源碼級(source-level)調試工具，可以用于Kernel模式調試和用戶模式調試，還可以調試Dump文件。

最新版安裝方法(此方法為在線安裝)

B.安裝netFramework2.0

C.運行1中下載的winsdk_web.exe

的symbol符號文件的路徑配置

為windebug設置symbol路徑可以提高對dump文件分析的準確性，給我們更多有價值的錯誤信息。

A．在http://msdn.microsoft.com/en-us/windows/hardware/gg463028.aspx根據實際需要下載相應的版本

B．安裝下載的symbol符號文件

詳細代碼如下

THREAD_STUCK_IN_DEVICE_DRIVER_M (100000ea)

The device driver is spinning in an infinite loop, most likely waiting for

hardware to become idle. This usually indicates problem with the hardware

itself or with the device driver programming the hardware incorrectly.

If the kernel debugger is connected and running when watchdog detects a

timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx()

and detailed message including bugcheck arguments will be printed to the

debugger. This way we can identify an offending thread, set breakpoints in it,

and hit go to return to the spinning code to debug it further. Because

KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck

information in this case. The arguments are already printed out to the kernel

debugger. You can also retrieve them from a global variable via

"dd watchdog!g_WdBugCheckData l5" (use dq on NT64).

On MP machines it is possible to hit a timeout when the spinning thread is

interrupted by hardware interrupt and ISR or DPC routine is running at the time

of the bugcheck (this is because the timeout's work item can be delivered and

handled on the second CPU and the same time). If this is the case you will have

to look deeper at the offending thread's stack (e.g. using dds) to determine

spinning code which caused the timeout to occur.

Arguments:

Arg1: 88a18908, Pointer to a stuck thread object.Do .thread then kb on it to find

the hung location.

Arg2: 88ced810, Pointer to a DEFERRED_WATCHDOG object.

Arg3: b84fbcbc, Pointer to offending driver name.

Arg4: 00000001, Number of times "intercepted" bugcheck 0xEA was hit (see notes).

通過紅色的代碼可以分析出這個藍屏是由于顯卡驅動引起的
