How to Upgrade Processor Speed (CPU)

A computer's central processing unit, or CPU, is sometimes referred to as the brain of a computer. A CPU carries out the millions of calculations necessary for a computer to operate. The speed of a CPU has a direct impact on the speed a computer can run its programs. Upgrading a processor's output speed can increase a computer's performance.

Limit start up applications. Many applications start up when your computer turns on that are unnecessary and slow down a CPU. Click "Start," then "Run," and type "msconfig" and click "OK." Go to the "Startup" tab and uncheck any startup services that you have installed since you got your computer but do not use. Programs like winamp, AIM, media players, and other programs often launch at startup, even though there is no need for them to do so.
