New System Suggestions

I think my Xps 410 system is on its last legs. My HD is starting to make a weird clicking sound which I assume means it is going bad. I am thinking about upgrading to a XPS 810 system and am looking for upgrade suggestions.  I just need good basic system since I am not a gamer and beyond watching a little Youtube and an occasional TV show do not due a lot of multimedia on the system. Thanks for any advice.
