Preamble:

When the computer frequently blue screen when we need software to find the cause of blue screen, at this time you can use Windbg software to analyze the blue screen file to find the cause.

Tools:

WinDbg software, there are two versions, you can refer to my previous article: installation and configuration of windbg symbol(symbol)

Methods/Steps:

1. First of all, we need to ensure that we set up a blue screen dump, so that when the computer blue screen, the system will retain the blue screen failure cause in the form of.dmp file, we need to query whether to set up a memory dump and blue screen file storage location. Right-click the desktop computer icon-select Properties, click Advanced System Settings, click Settings in the Startup and Recovery column, select Minidump in the Write Debug Information column (ignore this step if it is already set), Minidump directory is %SystemRoot%\Minidump(blue screen file storage location), that is, C:\Windows\Minidump folder.

The small memory dump is the information used to save the blue screen. The path to save the information is under the C:\Windwos\Minidump file. There must be a lot of dmp files under the folder. You can select and analyze them according to the time.

2. Open WinDbg software after viewing, first need to set symbol table path for WinDbg software, as blue screen cause analysis database, otherwise the software will have no effect. Click File--Select Symbol File Path, enter SRV*C:\Symbols* http://msdl.microsoft.com/download/symbols in the Symbol Path text box of the pop-up dialog box, and click OK.

3. Click File-Select Open Crash Dump to open the blue screen file, click C:\Windows\Minidump folder in the pop-up dialog box, click the blue screen file we want to analyze, click Open.
