There's nothing quite like the feeling of setting up a brand new computer, everything works perfectly and using it is a pleasure. The trouble is, it doesn't take long for it to accumulate folders, files and other junk which may all contribute to your machine behaving more erratically and performance becoming hindered. Although it's not quite time to call technical support, it may be time to try a diagnoses tool and attempt to identify any problems yourself. 10 Jun 2009
