I installed the Windows Debugger software at http://www.microsoft.com/whdc/devtoo...g/default.mspx. The software was placed in C:\Program Files\Debugging Tools for Windows (x64)\ I then opened the command prompt, changed directories and entered the address of the dmp file exactly as instructed at http://support.microsoft.com/kb/315263. The following is the command window text.

C:\Users\Cyberbiker>cd c:\program files\debugging tools for windows (x64)

c:\Program Files\Debugging Tools for Windows (x64)>windbg -z c:\Windows\Minidump\070211-21866-01.dmp

c:\Program Files\Debugging Tools for Windows (x64)>

However, the dumpchk.exe application presented the error windows below. For some reason it could not find the dmp file even though the directory address in my command entry was exactly what appeared in the transmittal report.

What could be wrong?

zigzag3143, "windbg -z DumpFilePath" was in the instructions at How to read the small memory dump files that Windows creates for debugging.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.

To ensure minidumps are enabled:

Go to Start, in the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and Recovery Settings... button.
Ensure that Automatically restart is unchecked.
Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (thy.e 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
OK your way out.
Reboot if changes have been made.

Attached is the zip archive containing my Minidump folde, which you requested in https://www.sevenforums.com/crashes-d...ay-driver.html. As you can see there have been many blue screens lately.

Thanks for sharing your knowledge.
