Synthesis Lags?

Hi, I have a question if any of you have experienced this occasionally, or ever.

As I type this thread right now, it's as if my synthesis is frozen. I wasn't lagging, my internet connection is working wonderfully- yet when I try to make things it doesn't always work, (very unpredictable, maybe happens every few days.) When it unfreezes, the synthesis ends up botching from the lag. How can I prevent this from happening..?

Thanks. (Sorry if I didn't post this thread in the correct place. ._. )

Mine only appears to hang when I launch a movie player or when loading a new movie to watch.

Might want to check what else is running on your system when the freezing occurs. My guess is that it will have something to do with DirectX.

Mine only does this when I am R0ing.
