When you suddenly notice that your computer is running slower than it did, the chances are that you have some spyware or adware working in the background that you were not aware of. However, once you have gotten rid of that, you might find that things like webpages open slower than they used to a while back. This is because the webpages themselves tend to have more on or in them than older webpages. As technology increases, the web designers make use of it, so you might have to do a little simple upgrade to your computer by adding some RAM, or random access memory.
