I have searched the net and found 1000 answers, none of which work.....

I rebooted my computer yesterday and this started. Win 7, lots of RAM and CPU. Worked fine for a few years. When playing a Netflix movie it suddenly lagged the audio about 1-2 seconds behind the video, as in the lips were not synced with the sound. I found this to be occurring in files played locally also, so it is not a Netflix or network related problem.
Did a "scorched earth" fresh install - including formatting the drive, and it is doing it still.

Any assistance from the brain-trust is appreciated.

Thank you.
