Greetings everyone! I recently purchased a Dell Inspiron 5521 for I have decided that it is finally time to replace my old laptop. The machine usually freezes when I play games on medium setting which I can play on high setting smoothly with my old laptop. I also notice that most  of the time when I'm browsing the web using firefox, the disk usage ranges from 90-100%.   I have included the basic system information necessary. Also I am playing the games on high-performance power setting and graphics properties. Can you please help me solve this problem? I wish to play games smoothly with this machine. Thank you.
