Have you every blue screened your computer and a cryptic stop code was delivered. What do you do now? Well, next time that happens, use Windbg to find out which application or driver is the culprit. You can download Windbg from Microsoft’s web site.
Simply set the debugger symbol path as follows, substituting your downstream store path for DownstreamStore.
For example, to download symbols to c:\websymbols, you would add the following to your symbol path: SRV*c:\websymbols*http://msdl.microsoft.com/
download/symbols and then click Files | Save Workspace..
Now you are ready to click File | Open Crash Dump and you can run diagnostics after a BSOD in safe mode.
