I'd just like to add to the advice given by Grandpa1, if you do a lot of internet surfing you will find that your PC will accumulate a lot of spyware and adware, which will slow your PC down.
Spyware and adware are downloaded to your PC without your knowledge and slows your PC down by secretly using your CPU, the only way to keep your PC up to speed is by getting rid of this internet “jetsam and flotsam”. You should download the following free products:
Ad-Aware SE 1.06

and
Spybot - Search and Destroy - 1.4
http://spybot.safer-networking.de/en/home/index.html
both products are very good individually but together they are great and will keep your machine up to speed.
