You can email it, or you can post it here. If you post it here, you will need to cut it into different posts as there is too much information in the text file (dxdiag.txt) to place in one post.
If you post it, all that is needed is the sections containing the computer, video, and sound sections. If there is something suspect from that, then I might need the entire thing via email.
Posting it allows it to be viewed, even when we are closed, like we are now, due to the weather.
