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)
