If you followed the directions to configure your system to create a crash dump file, here are some reasons why you might not see a crash dump file:

If you are not sure what you are seeing, do this:
Click Start, Run and in the box enter:
msinfo32
Click OK, and when the System Summary info appears, click Edit, Select All (Ctrl-A), Copy (Ctrl-C) and then paste (Ctrl-V) the information back here in your next reply.
There will be some personal information (like System Name and User Name), and whatever appears to be private information to you, just delete it from the pasted information.
This will minimize back and forth Q&A and eliminate guesswork.
