When I play a game or watch video my cpu usage jumps to 100% After about 15 min. my computer shuts off, just like pulling the power plug. I have done some investigating and I think I know why it shuts down, not sure why the cpu maxes out though.

I have a HP pavilion ze 5500 laptop with a pentium 4 running at 2.66 GHz
My graphics is a Radeon 1gp 345m I have 512 MB of RAM

I installed SpeedFan and while I'm playing the game (Xenotactic) I can watch the Temp on my cpu rise into the danger zone. I assume that once it reaches a certain temp it must trigger a sensor that shuts the computer off. I keep on eye on task mgr and my memory only increases about 10 meg but that puts it about 370m commit charge. I have have long intervals between playing games but I can't remember my computer ever shutting off before. I suspect dust build up inside my machine to be the cause of the heat?? I know I could use more RAM but I was wondering if part of my problem is the graphics card (not to knowledgeable in this area)

How big is your case, and can you take pictures of the insides of it?

Laptops are not really gaming devices...
You could use another 512MB of RAM for sure.
Get a can of compressed air and clean all vents. Elevate laptop to get better air flow.
