RE: Dell Inspiron 15 3558 SLOW

i am also using Inspiron 3558. Just three days purchased. Facing the problem of lagging. The letter shows up slower than my typing and when i scrolling the mouse, it lags from time to time. Not smooth. 

i am very disappointing with its performance. 

What is really going on? 

my spec is core i5-5200U cpu @ 2.20GHz,  4 G ram.
