First locate your minidump files, they are usually found by clicking on your C: drive, in Windows Explorer, then click on Windows to view the contents. If your operating system is installed under a different drive letter then look there. They should be stored under a file called minidump.The files will have a .dmp extension.
Zip up at least 6 of the most recent files into one zip folder and save on your desktop (if there are less then just zip up what you have).

Open Windows Explorer, click on Desktop in the left column so you can see the zip file. In the left column click on C: > Windows > Minidump and then drag & drop any additional .dmp files into the zip folder.
