Compaq Presario CQ50 Performance

I owned this laptop for several months (about 6 months). The problem that i always face with this laptop is the heat problem. Besides, the graphic is just nice for me. It is because im not the hardcore gamers. To run a light game will be no problem at all and i enjoy with the 15.4" screen. Really enjoy to watching the movie while im in the go. Can anyone who owned this model share with me how to improve and how does your laptop performance. I want to take some judgement over this info.Thanks
