Help me troubleshoot my video playback

Online videos play with no sound.

I recently began having a problem with my PC where videos will play without sound. This occurs somewhat randomly, and can often be fixed by reloading the video. The video sometimes (but not always) also freezes after a few seconds of silent playing, even though the playback indicator shows that it continues to download/buffer.
When the video plays w/o sound, the Windows sound mixer control does *not* show an audio signal. I have had a video with sound playing fine in one tab and a video with no sound in another, so this is not an intermittent connection or other global issue.
This happens with both HTML 5 and Flash video players, and in both Chrome and Firefox. I updated my video driver (GEForce 7300 SE) to no effect. I am running Windows Vista (I know....). Any thoughts as to possible causes, or ideas for further troubleshooting? I'm stumped.
