Why does my laptop sometimes get hot and cause its fan to rev up?
Your laptop, just like your car or body, can start to overheat when it's working or "thinking" really hard. The more programs you're running or the more complex your computer functions, the more your computer has to do -- and that can cause its central processing unit (CPU) to heat up. At that point, the fan turns on to cool down your laptop. If your laptop fan is constantly revving, you might need to upgrade your computer's CPU or get your fan cleaned to better handle the workload.

If your two- to three-year-old computer is sluggish, instead of getting a new model, you might just need to add more memory. You can do this yourself -- see your computer maker's web site for instructions about where to install additional memory once you purchase it.
