Shut down your computer, and let it sit for 30 seconds or so. Not a restart, do an actual shutdown. It might clear out something in the puter brain, then try to stream.... Just a suggestion.
Thanks, but I tried a complete 5 minute shutdown and ran Spybot. I defragged only a few days ago but I use so little of the total memory that it did little. Some of this stuff began after I installed Windows Media 10; I think I may go back to version 9.
