LanOC Questions 10/28/10

Marcello:I have laptop HP Pavilion dv7-2043cl. Recently I did an upgrade, I installed a Q9000 quadcore processor. I believe that the high temperature hit the video card (on board) ATI HD 4650 (has been repaired). I'm a gamer and I need you guys to indicate the best cooler for my profile. Please help me, I do not want to lose my laptop and my money.
