My new computer arrived Tuesday.
I am working on getting all my software installed. (I am installing my scanner software as I type.)
I spent almost 2 hours troubleshooting sound issues (my speakers were connected, device driver was latest version) on Wednesday. I walked away for 45 minutes, the speakers were working when I came back. (and a restart was not involved??)
And my fingers are crossed that my Windows backed up files will restore correctly.
