I figured it out.
I had recently added a Wireless card. When I disabled it, the problem seems to have gone away. I re-enabled it and got the problem again. I'll monitor and see what happens.
BTW, I had already moved my USB connection to the rear of the computer, Set power to high performance, Adjusted the Toneport buffers, checked on USB drivers and all other drivers. I never got to the special site on USB drivers.
When I used my head phones in the Toneport jack, I get the issue. When I use my headphones on the headphone jack on the front of the computer, I do not have the issue.
Thanks for throwing me a troubleshooting link.
