So what does significantly increase a computer's speed?

1. Adding more RAM.  The more the better.

2. Reducing the amount of programs which load themselves at start up.  This can be done with the MSCONFIG utility.  Many computers have way too much loading at start up, most of which is unnecessary.

3. Stopping unnecessary services from running.  A service in Windows is essentially a program which runs in the background and provides some functionality for either Windows or an installed program.  One example of a service is "Bonjour," a mostly unnecessary service which is loaded when ITunes is installed.

Sometimes, a computer is just so old that none of these solutions can bring the results one wants.  In that case, it's time to break down and buy a new computer.  No software can cure old!
