Upload Dump Files
Please go to C:\Windows\Minidump and zip up the contents of the folder. Then upload/attach the .zip file with your next post.
{Left click on the first minidump file.
Hold down the "Shift" key and left click on the last minidump file.
Right click on the blue highlighted area and select "Send to"
Select "Compressed (zipped) folder" and note where the folder is saved.
Upload that .zip file with your next post.}

If you have issues with "Access Denied" errors, try copying the files to your desktop and zipping them up from there. If it still won't let you zip them up, post back for further advice.

If you don't have anything in that folder, please check in C:\Windows for a file named MEMORY.DMP. If you find it, zip it up and upload it to a free file hosting service - then post the link to it.
Then, follow the directions here to set your system for Minidumps (much smaller than the MEMORY.DMP file): Set MiniDump
