Use Everest to get a report of your system’s hardware, OS, and drivers. Upload the report as an attachment
Everest: http://www.majorgeeks.com/download.php?det=4181

Click "Report" at the top of the Everest window, click next to get to "Report Profile", select "Hardware-related Pages", click next, select "Plain Text", click "Finish". Then when it is done processing, click "Save To File". Save it where you want to. (I would use Desktop.)
Click "Go Advanced" in the MG reply box, scroll down a little way until you see "Manage Attachments", click it, browse to your file, click "Upload", and close the window. Then submit the post. You may have to also type something in the reply box, like, "Here's my report.", so that it will submit.
