Whenever Windows crashes it generates a Dump (*.dmp) file that contains the log of the crash. All you have to do is to analyze the log to see who is responsible for the crash. In most cases its a driver. To analyze the dump you need a program from Microsoft called WinDebug.
- Install WinDebug. It can be downloaded from Microsoft's web site. It's pretty big!
- Install it in a folder like: "c:\Program Files\!system\WinDbg\Symbols"
- Once installed run it and hurry to "File | Symbol
File Path" menu and enter this string: SRV*c:\Program Files\!system\WinDbg\Symbols2\*http://msdl.microsoft.com/download/symbols
and wait... It may take quite a while for the download to finish... up to 10 minutes. The program will look like it it doesn't download anything. But when the download will be ready you will finally see a message.
- Load the Dump file (menu 'File | Open crash dump'). You can manually search for the DMP file in Windows. However, I recommend you 'W7F Diagnostic Tool.exe' tool to locate/extract the DMP file.
- Enter this command to analyze the file: kd> !analyze -v
Note: you don't have to write kd>. It is already there.
The log will say "Bugcheck Analysis" and the command prompt will say "Bussy". It may take a while, then the command prompt will return to 'kd>'.
- Analyze the log and find out who is at fault.
The log may look like this. I will highlight interesting parts:
A driver is causing an inconsistent power state.
Arg1: 00000003, A device object has been blocking an Irp for too long a time
Arg2: 86cc1b58, Physical Device Object of the stack
Arg3: 83172ae0, Functional Device Object of the stack
Arg4: 8957d8a0, The blocked IRP

The last line is the MAGIC line that we are interested in. It shows that network's card driver is the one that causes the blue screen!
That a fucking Realtek driver for a Realtek 8192 network card. I updated the driver many times but it continues to be buggy.
Solution: I will send the network card back and ask for a refund!
