Part: XI Upgrading Your Main System Components > Upgrading Your CPU and BIOS

Chapter 37. Upgrading Your CPU and BIOS

You learned in the last chapter that upgrading your PC's memory is the first part of the performance upgrade equation. Upgrading your computer's CPU (central processing unit, also called the processor or microprocessor) is the other half of the coin if you want to beef up your PC's performance. The CPU is the brain inside your PC. The CPU processes the instructions in your programs and operating system and is the single most important factor in improving your PC's raw computing speed.

And while many users exist who have given some thought to upgrading their CPU, most still don't give a second thought about upgrading their BIOS (Basic Input/Output System). Some PCs need a BIOS upgrade if they are to accept an upgraded processor. And some PCs need a BIOS upgrade to work with a removable media drive or some other new technology that will soon be coming down the pike. This chapter shows you how to upgrade both your CPU and your system BIOS.
