Upgrading a computer

When you upgrade a computer you usually replace older components with new components to improve the performance of a computer. you can also upgrade a computer by adding additional components, such as more memory or a second hard drive. Upgrading a computer to improve its performance is often cheaper than buying a new computer. For most upgrading you will need someone with a lot of computer experience to do the upgrade for you. It's often difficult to determine which is better- upgrading an old computer or simply buying a new computer. If you're an average computer user, plan on buying a new computer every four or five years (sorry -someone has to break this news to you). By then, the of a new computer will be less expensive than any effective upgrades you do.
