RE: Dell XPS 15 L502x buzzing and stuttering problems persist even after uninstalling Dell SupportAssist
Same problems as others with Inspiron 1570, Windows 7. Tried uninstalling Support Assist Agent. Did not solve problem. Then uninstalled Support Assist as well. Problem still occurring. As others have said elsewhere there is a buzz/freeze on video playback at intervals of around a minute but even this is not consistent. Problem first experienced Friday 13 Feb (UK time).
