Laptop keeps on freezing

[lexluth0r]

I have a Compaq Presario V4000 Notebook which keeps on freezing, the only way to unfreeze the thing is hit it with your hand (to the right of the mouse pad), the laptop is fine went its on a table but if you put it on your lap it would keep on freezing. I've removed and put back the RAM but the problem still continuous. The laptop is now out of warranty so I can't send it back to Compaq so does anyone know what I would need to replace to sort it?

You need to clean the CPU fan,or the fan may be going bad.

You may also consider a laptop cooler.--->SearchHere

I have one of those. Very nice.

Though it is called a laptop, it is not recommended you use it on your lap because it gets too hot.

Which is why I use the term "notebook PC". Laptops don't always function well on laps.
