Hi there, Zip,
Brought my Featherduster out, and even a gentle vacuum and cleaned everything out as best I could, but to no avail. The next time I turned on the computer, the internet lasted only 10 minutes. *Sigh* I thought it was a good idea, too, although it really wasn't too dusty in there, as I remember opening the computer up and doing that about a year ago.
Thank you for the suggestion, though!
Mrs. Lufbra/Featherduster
