the solution to laptop overheating

 

Honestly,after seeing those computer specs your laptop isn't decent tho.
You should atleast have 2gb ram and 80 or more hard disc and even a 512 mb gfx card if possible.

I use my sis's laptop this is its specs:
4gb ram
256 gb hard disc
Windows vista.
512 mb video card(geforce)
with a finger print reader and a webcam
its HP dv4 but it gets heated up quickly.
