RE: Dell XPS 15 L502x buzzing and stuttering problems persist even after uninstalling Dell SupportAssist

Having seen http://en.community.dell.com/support-forums/laptop/f/3518/p/19618339/20728342#20728342 I stopped Dell Data Vault and Dell Data Vault Wizard services starting (using Autoruns). No more buzzing, even with Dell Support Assist re-installed, although video performance still seems slow. I haven't re-installed Dell Support Assist Agent.
