help with gaming problem

I seem to have a problem with my Dell 600m laptop. Whenever I play certain
games, like Madden 2004 or Need for Speed Hot Pursuit 2, it runs perfectly
for about 10 or 15 minutes, then the graphics get very choppy and it makes
it impossible to play. I've run AdAware, Spybot S&D, and anti-virus. I
also Defragged my hard drive. Is there anything else I can do. Thanks

The system is probably getting too hot. Take the cover off the case and
see if that helps. Also, get a can of compressed air and blow out the
dust bunnies. Do not use a vacuum cleaner to clean the insides!

 

you did read the first line correctly did you?

 

yes. don't use a laptop for high end gaming. your system is way too hot! and
your graphics card probably doesn't have its own cooler.

 

OK, so taking the cover off is a bit more difficult... ;-)
