Youtube videos sound garbled xp

Try this:

Run the Task Manager
Go to the options, and check hide when minimized
Minimize it; you should now see it by the clock, and it will show you a graph of how much your CPU is being used.
Run a video

If the task manager shows very high CPU usage you either have a video driver problem or your CPU is overheating and running slow.

thank you got so frustrated that got my older desktop connected and no problems there. will do this when I connect desktop again and I have oodles of time to continue troubleshooting.

happy holidays
