The results of your test should be in C:\Windows\System32\LogFiles\MemDiag\MemDiag.bin. I would suggest you run memtest86,
and run it to where you check not only the ram but the dimm slots. It is a long testing process but the linked tutorial will explain in detail how the test should be run. You may also want to read this tutorial
in posting in the crashes and debugging section of the forums. The tests will give them the information to help resolve your issues. The dump files can be located in C:/windows/minidump. Copy and paste the contents of that folder somewhere easy to get to. Right click them and select send to compressed folder and upload that with the other tests using the paperclip icon in the reply window.
