Games bouncing back and forth between laggy and smooth??

    Hey everyone, I have been trying to play a few games on my laptop recently, and I've noticed the oddest thing. Take Dungeon Siege 2 for example; I start the game up, graphics are set to high, and the game runs smooth as butter. About 5 minutes go by and then I hit a massive lag spike, my frame-rate drops from 40 to 10. This lasts for about another 5minutes then... its back to being smooth again? It will keep doing this switch back and forth constantly. The game only uses about 400mb of ram, and even when its being laggy, lowering the graphics to bare-bones doesn't make the slightest difference.

    I tried setting the core affinity to 1, 2 or both, that doesn't seem to make anything better. I tried raising the app priority, but vista keeps reseting it i think. And oddly, by minimizing the game and waiting about 30seconds, the game will go back to being smooth again.
    What is going on??

    Specs:
    Vista Home Premium
    NVIDIA GeForce 8600M GT
    Intel Core 2 Duo CPU T7500 @ 2.20GHz (2 CPUs), ~2.2GHz
    2046MB RAM

    Any other programs or tasks running in the background?
    such as an active antivirus/spyware scanner?

    Sounds like something is using CPU time every 5 or so min and slowing the game down.
    And, be sure your hard drive is defragmented. Helps the game find it's files faster.

    Yah that's what I thought at first but I found out what's going on. Every 5min or so the temp on my laptop cores rises to 95C !! Then I guess the computer tries to cool itself down by shutting down one of the cores or something for a little bit. Then once it's cooled it runs fine again.

    I know how to fix heat issues on a PC, not a laptop, what should i do?

    awesome, thanks for the link. I'm going to try opening it up and cleaning it out a bit first, then if that doesn't work i'll probably go with the pad
