Windows keep lagging, although laptop has high specifications

Hey all

I have a problem with my laptop, and it really bothers me !

My laptop has high specifications , but still it easily start lagging if i open multiple applications ,I even changed from kaspersky to MSE ,to make it less pressure on it ! but if I only open firefox,skype,msn, and VLC , it start lagging ,and the mouse just keep pausing and moving, I either stopped comodo firewall ! but still sometimes it does !

I recently formatted the laptop as well, and the laptop heating is bad sometimes ,but I try my best to keep it cool ! and i suppose it's not the problem

any idea how to fix that ,because I suppose my laptop could get much more ! and when it lags i check the CPU usage ,and it's not that much as well

That's a picture shows my laptop specifications

my laptop is
HP Pavilion DV6 i7
and Windows 7 64bit
