Minidump (small memory dump) files are logs that are created/updated with debugging information every time a BSOD occurs.
To begin, click the Start Menu or Search Icon and type "Control Panel", then click the entry that appears:
Now click System and Security from within the Control Panel:
Then click System from the list:
Now, click Advanced System Settings:
Under the Start-up and Recovery section, click Settings:
Finally, select Small Memory Dump from the debugging drop-down menu, disable "automatically restart" and then click OK:
Minidumps are now enabled and will be created.
(If you wish to reset the settings back to default, please repeat the steps, but choose "Automatic memory dump" at the last stage.)
The minidump files will be located in %SystemRoot%\Minidump, which is generally C:\Windows\Minidump.
Please reproduce the problem, zip the Minidump files up first, and attach them to your next email.
